The chemistry of lead in drinking water

Our county, like many in the US and Canada, is served by thousands of miles of lead pipes. Some of these are the property of the government, others sit beneath our homes and are the property of the home-owner. These pipes are usually safe, but sometimes poison us. There is also problem of lead-tin solder. It was used universally to connect iron and copper pipes until it was outlawed in 1986. After years of sitting quietly, this lead caused a poisoning crisis in DC in 2004, and in Flint in 2015-16. Last month my town, Oak Park, registered dangerous lead levels in the drinking water. In an attempt to help, please find the following summary of the relevant lead chemistry. Maybe people in my town, or in other towns, will find some clue here to what’s going on, and what they can do to fix it.

lead pipes showing the three oxides: brown, yellow, and red, PbO2, PbO, and Pb2O3.

Left to itself, lead and solder pipe could be safe; lead is not soluble in clean water. But, if the water becomes corrosive, as happens every now and again, the lead becomes oxidized to one of several compounds that are soluble. These oxides are the main route of poisoning; they can present serious health issues including slow development, joint and muscle pain, memory issues, vomiting, and death. The legal limit for lead content in US drinking water is 15 ppb, a level that is far below that associated with any of the above. The solubility of PbO, lead II oxide, is more than 1000 times this limit 0.017 g/L, or 17,000 ppb. At this concentration serious health issues will show up.

PbO is the yellow lead oxide shown in the center of the figure above, right; the other pipes show other oxides, that are less-soluble, and thus less dangerous. Yellow lead oxide and red lead oxides on the right were used as paint colors until well into the 20th century. Red lead oxide is fairly neutral, but yellow PbO is a base; its solubility is strongly dependent on the PH of the water. In neutral water, its solution can be described by the following reaction.

PbO + H2O(l) –> Pb2+(aq) + 2 OH(aq).

In high pH water (basic water), there are many OH(aq) ions, and the solubility is lower. In low pH, acidic water the solubility is even higher. For every 1 point of lower pH the lowubility increases by a factor of 10, for every 1 point of higher pH, it decreases by a factor of ten. In most of our county, the water is slightly basic, about pH 8. It also helps that our water contains carbonate. Yellow lead forms basic lead carbonate, 2PbCO3·Pb(OH)2, the white lead that was used in paint and cosmetics. Its solubliity is lower than that of PbO, 110 ppb, in pure water, or within legal limit in water of pH 8. If you eat white lead, though, it reacts with stomach acid, pH 2, and becomes quite soluble and deadly. Remember, each number here is a factor of ten.

A main reason lead levels a very low today are essentially zero, even in homes with lead solder or pipe, involves involves the interaction with hypochlorite. Most water systems add hypochlorite to kill bacteria (germs) in the water. A side benefit is significant removal of lead ion, Pb2+(aq).

Pb2+(aq) + 2 ClO(aq) –> Pb(ClO)2(s). 

Any dissolved lead reacts with some hypochlorite ion reacts to form insoluble lead hypochlorite. Lead hypochlorite can slowly convert to Lead IV oxide — the brown pyrophilic form of lead shown on the left pipe in the figure above. This oxide is insoluble. Alkaline waters favor this reaction, decreasing solubility, but unlike with PbO, highly alkaline waters provide no significant advantage.

PbClO+(aq) + H2O(l) –> PbO2(s) + 2 H+(aq) + Cl(aq)

Lead IV oxide, PbO2 was used in old-fashioned matches; it reacts violently with phosphorus or sulfur. People were sometimes poisoned by sucking on these matches. In the stomach, or the presence of acidic drinking water, PbO2 is decomposed forming soluble PbO:

PbO2(s) +2 H+(aq) + 2 e –> PbO(s) + H2O(l).

You may wonder at the presence of the two electrons in the reaction above. A common source in water systems is the oxidation of sulphite:

SO3-2(aq)–> SO4-2(aq) + 2 e.

The presence of sulphite in the water means that hypochlorite is removed.

ClO(aq) + 2 H+(aq) + 2 e —> Cl(aq) + H2O(l).

Removal of hypochlorite can present a serious danger, in part because the PbO2(s) slowly reverts to PbO and becomes soluble, but mostly because bacteria start multiplying. In the Flint crisis of 2016, and in a previous crisis in Washington DC, the main problem, in my opinion was a lack of hypochlorite addition. The lead crisis was preceded by an uptick in legionnaires disease; It killed 12 people in Flint in 2014 and 2015, and 87 were sickened, all before the lead crisis. Eventually, it was the rise of legionaries disease that alerted water officials in Virginia that there was something seriously wrong in Flint. Most folks were unaware because Flint water inspectors seem to have been fudging the lead numbers to make things look better.

Most US systems add phosphate to remove lead from the water. Flint water folks could have stopped the lead crisis, but not the legionnaires, by adding more phosphate. Lead phosphate solubility is 14 ppb at 20°C, and my suspicion is that this is the reason that the legal limit in the US is 15 ppb. Regulators chose 15 ppb, I suspect, not for health reasons, but because the target could be met easily through the addition of phosphate. Some water systems in the US and Canada disinfect with chloramine, not hypochlorite, and these systems rely entirely on phosphate to keep lead levels down. Excess phosphate is used in Canada to lower lead levels below 10 ppb. It works better on systems with hypochlorite.

Chloramine is formed by reacting hypochlorite with ammonia. It may be safer than hypochlorite in terms of chlorite reaction products, a real problem when the water source is polluted. But chloramine is not safe. It sickened 72 soldiers, 36 male and 36 female in 1998. They’d used ammonia and bleach for a “cleaning party” on successive days. Here’s a report and first aid instructions for the poisoning. That switching to chloramine can expose people to lead is called “the chloramine catch”.

Unlike PbO, PbO2 is a weak acid. PbO2 and PbO can react to form red lead, PbO•PbO2(s), the red stuff on the pipe at right in the picture above. Red lead can react with rust to form iron plumbable, an insoluble corrosion resister. A simple version is:

PbO•PbO2(s) + Fe2O3(s) —> 2FePbO3(s).

This reaction is the basis of red-lead, anti-rust compounds. Iron plumbable is considered to be completely insoluble in water, but like PbO it is soluble in acid. Bottom line, slightly basic water is good, as are hypochlorite in moderation, and phosphate.

Robert Buxbaum, November 18, 2019. I ran for water commissioner, and might run again. Even without being water commissioner, I’ll be happy to lend my expertise, for free, to any Michigan town or county that is not too far from my home.

Water Towers, usually a good thing.

Most towns have at least one water tower. Oakland county, Michigan has four. When they are sized right, they serve several valuable purposes. They provide water in case of a power failure; they provide increased pressure in the morning when people use a lot of water showering etc.; and they allow a town to use smaller pumps and to pump with cheaper electricity, e.g. at night. If a town has no tower, all these benefits are gone, but a town can still have water. It’s also possible to have a situation that’s worse than nothing. My plan is to show, at the end of this essay, one of the ways that can happen. It involves thermodynamic properties of state i a situation where there is no expansion headspace or excess drain (most towers have both).

A typical water tower — spheroidal design. A tower of the dimensions shown would contain about 1/2 million gallons of water.

The typical tower stands at the highest point in the town, with the water level about 170 feet above street level. It’s usable volume should be about as much water as the town uses in a typical day. The reason for the height has to do with the operating pressure of most city-level water pipes. It’s about 75 psi and each foot of water “head” gives you about 0.43 psi. You want pressures about 75 psi for fire fighting, and to provide for folks in apartment buildings. If you have significantly higher pressures, you pay a cost in electricity, and you start losing a lot of water to leaks. These leaks should be avoided. They can undermine the roads and swallow houses. Bob Dadow estimates that, for our water system the leakage rate is between 15 and 25%.

Oakland county has four water towers with considerably less volume than the 130 million gallons per day that the county uses. I estimate that the South-east Oakland county tower, located near my home, contains, perhaps 2 million gallons. The other three towers are similar in size. Because our county’s towers are so undersized, we pay a lot for water, and our water pressure is typically quite low in the mornings. We also have regular pressure excursions and that leads to regular water-boil emergencies. In some parts of Oakland county this happens fairly often.

There are other reasons why a system like ours should have water towers with something more like one days’ water. Having a large water reserve means you can benefit from the fact that electric prices are the lowest at night. With a days’ volume, you can avoid running the pumps during high priced, day times. Oakland county loses this advantage. The other advantage to having a large volume is that it gives you more time to correct problems, e.g. in case of an electric outage or a cyber attack. Perhaps Oakland thinks that only one pump can be attacked at one time or that the entire electric grid will not go out at one time, but these are clearly false assumptions. A big system also means you can have pumps powered by solar cells or other renewable power. Renewable power is a good thing for reliability and air pollution avoidance. Given the benefits, you’d expect Oakland county would reward towns that add water towers, but they don’t, as best I can tell.

Here’s one way that a water column can cause problems. You really need those pressure reliefs.

Now for an example of the sort of things that can go wrong in a water tower with no expansion relief. Every stand-pipe is a small water tower, and since water itself is incompressible, it’s easy to see that a small expansion in the system could produce a large pressure rise. The law requires that every apartment hose water system has to have expansion relief to limit these increases; The water tower above had two forms of reliefs, a roof vent, and an overflow pipe, both high up so that pressure could be maintained. But you can easily imagine a plumber making a mistake and installing a stand pipe without an expansion relief. I show a system like that at left, a 1000 foot tall water pipe, within a skyscraper, with a pump at the bottom, and pipes leading off at the sides to various faucets.

Lets assume that the pressure at the top is 20 psi, the pressure at the bottom will be about 450 psi. The difference in pressure (430 psi) equals the weight of the water divided by the area of the pipe. Now let’s imagine that a bubble of air at the bottom of the pipe detaches and rises to the top of the pipe when all of the faucets are closed. Since air is compressible, while water is not, the pressure at the bubble will remain the same as the bubble rises. By the time the bubble reaches the top of the pipe, the pressure there will rise to 450 psi. Since water has weight, 430 psi worth, the pressure at the bottom will rise to 880 psi = 450 + 430. This is enough to damage pump and may blow the pipes as well. A scenario like this likely destroyed the New Horizon oil platform to deadly consequences. You really want those pressure reliefs, and you want a competent plumber / designer for any water system, even a small one.

Why does water cost what it does?

Water costs vary greatly about Oakland county, and around the US, and I have struggled in vain to find out why. In part the problem is that each city gets to add as much maintenance and management costs as the city government thinks appropriate. High management and infrastructure fees can increase to the cost of water, but I also not that different cities about Oakland County Michigan get their water at different rates from the multi-county organization that oversees water in South East Michigan: GLWA, The Great Lakes Water Authority.

$112 water bill for zero usage. The base charge is so large that prices are essentially independent of useage.

I’ve attended meetings, both local and multi county and have tried to find out why one town gets its water at a far lower rate than another, near by. Towns get lower rates if they have a water tower, but it is not at all clear what the formula is. It also helps to separate the storm sewage from the sanitary sewage — something that I have proposed for all of Oakland county, but if there is fixed formula of how that affects rates, I’ve not seen it. And I wonder how well communities monitor the amount of storm sewage they generate.

The water itself is free. For the most part, in this county, we pump it from the Detroit river. Some of the rest of the water is pumped from wells. None of this costs anything. There is a pump cost, but it is manicure. Pumping 1 gallon of water up 75 feet, costs about 0.002¢ in pumping cost. The rest of the cost is infrastructure: the cost of the pumps, the pipes, the treatment, the billing and sewage. Among the sewage fees is a pollution penalty, and Oakland county pays plenty of pollution penalties. When it rains, we generate more sewage than the system will handle, and we dump the rest into the rivers and lakes. This results in closed beaches and poisoned fish, and fines too. The county pays the EPA when we do this, and the county passes the cost to the cities. I don’t know what the formula for fee distribution is, and don’t even know what it should be. What I do know is that we do this vastly too often.

Another oddity is that we bill on a per gallon basis. For my home, the bill is about 2¢/ gallon — 100 times the pumping cost. Though the city can claim that we are paying for infrastructure, both clean water infrastructure and sewage infrastructure, it seems odd to bill on a per-gallon used basis, and 1000 times the true per-gallon price. Since most of the price of water is the infrastructure and management cost, it seems like a regressive tax to charge people on the basis of per-gallon used. I also find it odd that cities do a propaganda campaign to tell folks to use less water. Why? I’d much prefer to charge a far lower base charge, and then bill significantly per-gallon. As with much that is socialist, the current system is inefficient, but pleasant for the management.

Kindness and Cholera in California

California likely leads the nation in socially activist government kindness. It also leads the nation in homelessness, chronic homelessness, and homeless veterans. The US Council on Homelessnesses estimates that, on any given day, 129,972 Californians are homeless, including 6,702 family households, and 10,836 veterans; 34,332 people are listed among “the chronic homeless”. That is, Californians with a disability who have been continuously homeless for one year or cumulatively homeless for 12 months in the past three years. No other state comes close to these numbers. The vast majority of these homeless are in the richer areas of two rich California cities: Los Angeles and San Francisco (mostly Los Angeles). Along with the homeless in these cities, there’s been a rise in 3rd world diseases: cholera, typhoid, typhus, etc. I’d like to explore the relationship between the policies of these cities and the rise of homelessness and disease. And I’d like to suggest a few cures, mostly involving sanitation. 

A homeless encampment in LosAngeles

Most of the US homeless do not live in camps or on the streets. The better off US homelessness find it is a temporary situation. They survive living in hotels or homeless shelters, or they “couch-serf,” with family or friends. They tend to take part time jobs, or collect unemployment, and they eventually find a permanent residence. For the chronic homeless things are a lot grimmer, especially in California. The chronic unemployed do not get unemployment insurance, and California’s work rules tend to mean there are no part time jobs, and there is not even a viable can and bottle return system in California, so the homeless are denied even this source of income*. There is welfare and SSI, but you have to be somewhat stable to sign up and collect. The result is that California’s chronic homeless tend to live in squalor strewn tent cities, supported by food handouts.

Californians provide generous food handouts, but there is inadequate sewage, or trash collection, and limited access to clean water. Many of the chronic homeless are drug-dependent or mentally ill, and though they might  benefit from religion-based missions, Los Angeles has pushed the missions to the edges of the cities, away from the homeless. The excess food and lack of trash collection tends to breed rats and disease, and as in the middle ages, the rats help spread the diseases. 

Total homelessness by state, 2018; California leads the nation. The better off among these individuals do not live on the streets, but in hotels or homeless shelters. For most, this is a short term situation. The rest, about 20%, are chronically homeless. About half of these live on the streets without adequate sewage and water. Many are drug-dependent.

The first major outbreaks of the homeless camps appeared in Los Angeles in August and September of 2017. They reappeared in 2018, and by late summer, rates were roughly double 2017’s. This year, 2019, looks like it could be a real disaster. The first case of a typhoid infected police officer showed up in May. By June there were six police officers with typhoid, and that suggests record numbers are brewing among the homeless.

To see why sanitation is an important part of the cure, it’s worth noting that typhoid is a disease of unclean hands, and a relative of botulism. It is spread by people who go to the bathroom and then handle food without washing their hands first. The homeless camps do not, by and large, have hand washing stations. and forced hygiene is prohibited. Los Angeles has set up porta-potties, with no easy hand washing. The result is typhoid epidemic that’s even affecting the police (six policemen in June!).

rate od disease spread.
R-naught, reproduction number for some diseases, CDC.

Historically, the worst outbreaks of typhoid were spread by food workers. This was the case with “typhoid Mary of the early 20th century.” My guess is that some of the police who got typhoid, got it while trying to feed the needy. If so, this fellow could become another Typhoid Mary. Ideally, you’d want shelters and washing stations where the homeless are. You’d also want to pickup the dirtier among the homeless for forced washing and an occasional night in a homeless shelter. This is considered inhumane in Los Angeles, but they do things like this in New York, or they did.

Typhus is another major disease of the California homeless camps. It is related to typhoid but spread by rodents and their fleas. Infected rodents are attracted to the homeless camps by the excess food. When the rodents die, their infected fleas jump to the nearest warm body. Sometimes that’s a person, sometimes another animal. In a nastier city, like New York, the police come by and take away old food, dead animals, and dirty clothing; in Los Angeles they don’t. They believe the homeless have significant squatters rights. California’s kindness here results in typhus.

Reproduction number and generation time for some diseases.

The last of the major diseases of the homeless camps is cholera. It’s different from the others in that it is not dependent on squalor, just poor health. Cholera is an airborne disease, spread by coughing and sneezing. In California’s camps, the crazy and sick dwell close to each other and close to healthy tourists. Cholera outbreaks are a predictable result. And they can easily spread beyond the camps to your home town, and if that happens a national plague could spread really fast.

I’d discussed R-naught as a measure of contagiousness some months ago, comparing it to the reproductive number of an atom bomb design, but there is more to understanding a disease outbreak. R-naught refers merely to the number of people that each infected person will infect before getting cured or dying. An R-naught greater than one means the disease will spread, but to understand the rate of spread you also need the generation time. That’s the average time between when the host becomes infected, and when he or she infects others. The chart above shows that, for cholera, r-naught is about 10, and the latency period is short, about 9 days. Without a serious change in California’s treatment of the homeless, each cholera case in June will result in over 100 cases in July, and well over 10,000 in August. Cholera is somewhat contained in the camps, but once an outbreak leaves the camps, we could have a pandemic. Cholera is currently 80% curable by antibiotics, so a pandemic would be deadly.

Hygiene is the normal way to prevent all these outbreaks. To stop typhoid, make bathrooms available, with washing stations, and temporary shelters, ideally these should be run by the religious groups: the Salvation Army, the Catholic Church, “Loaveser and Fishes”, etc. To prevent typhus, clean the encampments on a regular basis, removing food, clothing, feces and moving squatters. For cholera, provide healthcare and temporary shelters where people will get clean water, clean food, and a bed. Allow the homeless to work at menial jobs by relaxing worker hiring and pay requirements. A high minimum wage is a killer that nearly destroyed Detroit. Allow a business to hire the homeless to sweep the street for $2/hour or for a sandwich, but make a condition that they wash their hands, and throw out the leftovers. I suspect that a lot of the problems of Puerto Rico are caused by a too-high minimum wage by the way. There will always be poor among you, says the Bible, but there doesn’t have to be typhoid among the poor, says Dr. Robert Buxbaum.

*California has a very strict can and bottle return law where — everything is supposed to be recycled– but there are very few recycling centers, and most stores refuse to take returns. This is a problem in big government states: it’s so much easier to mandate things than to achieve them.

July 30, 2019. I ran for water commissioner in Oakland county, Michigan, 2016. If there is interest, I’ll run again. One of my big issues is clean water. Oakland could use some help in this regard.

How to avoid wet basements

My house is surrounded my mulch — it absorbs enough rainwater that I rarely have to water.

Generally speaking water gets to your basement from rain, and the basic way you avoid wet basements is by providing some more attractive spot for the rainwater to go to. There are two main options here: divert the water to a lake or mulch-filled spot at least 8 feet away from your home, or divert it to a well-operated street or storm drain. My personal preference is a combination of both.

At right I show a picture of my home taken on a particularly nice day in the spring. Out front is a mulch-filled garden and some grass. On the side, not shown is a driveway. Most of the rain that hits our lawn and gardens is retained in 4 inches of mulch, and waters the plants. Four inches of mulch-covered ground will hold at least four inches of rainwater. Most of the rain that hits the house is diverted to downspouts and flows down the driveway to the street. Keeping some rainwater in the mulch means you don’t have to pay so much to water the trees and shrubs. The tree at the center here is an apple tree. I like fruit trees like this, they really suck up water, and I like the apples. We also have blueberries and roses, and a decorative pear (I like pears too, but they are messy).

In my opinion, you want some slope even in the lawn area, so excess rainwater will run to the sewers and not form a yard-lake, but that’s a professional preferences; it’s not always practical and some prefer a brief (vernal ) lake. A vernal lake is one that forms only in the spring. If you’ve got one, you may want to fill it with mulch or add trees that are more water tolerant than the apple, e.g. swamp oak or red cedar. Trees remove excess water via transpiration (enhanced evaporation). Red Cedars grow “knees” allowing them to survive with their roots completely submerged.

For many homes, the trick to avoiding a flooded basement is to get the water away from your home and to the street or a retention area.

When it comes to rain that falls on your hose, one option is to send it to a vernal lake, the other option is to sent it to the street. If neither is working, and you find water in your basement, your first step is to try to figure out where your rainwater goes and how it got there. Follow the water when it’s raining or right after and see where it goes. Very often, you’ll discover that your downspouts or your driveway drain into unfortunate spots: spots that drain to your basement. To the extent possible, don’t let downspout water congregate in a porous spot near your house. One simple correction is to add extenders on the downspouts so that the water goes further away, and not right next to your wall. At left, I show a simple, cheap extender. It’s for sale in most hardware stores. Plastic or concrete downspout pans work too, and provide a good, first line of defense agains a flood basement. I use several to get water draining down my driveway and away from the house.

Sometimes, despite your best efforts, your driveway or patio slopes to your house. If this is the case, and if you are not quite ready to replace your driveway or patio, you might want to calk around your house where it meets the driveway or patio. If the slope isn’t too great, this will keep rainwater out for a while — perhaps long enough for it to dry off, or for most of the rainwater to go elsewhere. When my driveway was put in, I made sure that it sloped away from the house, but then the ground settled, and now it doesn’t quite. I’ve put in caulk and a dirt-dam at the edge of the house. It keeps the water out long enough that it (mostly) drains to the street or evaporates.

A drain valve. Use this to keep other people’s sewer water out of your basement.

There is one more source of wet basement water, one that hits the houses in my area once a year or so. In our area of Oakland county, Michigan, we have combined storm and sanitary sewers. Every so often, after a big rain, other people’s rainwater and sanitary sewage will come up through the basement drains. This is really a 3rd world sewer system, but we have it this way because when it was put in, in the 1900s, it was first world. One option if you have this is to put in a one-way drain valve. There are various options, and I suggest a relatively cheap one. The one shown at right costs about $15 at Ace hardware. It will keep out enough water, long enough to protect the important things in your home. The other option, cheaper and far more hill-billy, is to stuff rags over your basement drains, and put a brick over the rags. I’ll let you guess what I have in my basement.

Why concrete cracks and why sealing is worthwhile

The oil tanker Palo Alto is one of several major ships made with concrete hulls.

The oil tanker Palo Alto is one of several major ships made with concrete hulls.

Modern concrete is a wonderful construction material. Major buildings are constructed of it, and major dams, and even some ships. But under the wrong circumstances, concrete has a surprising tendency to crack and fail. I thought I’d explain why that happens and what you can do about it. Concrete does not have to crack easily; ancient concrete didn’t and military or ship concrete doesn’t today. A lot of the fault lies in the use of cheap concrete — concrete with lots of filler — and with the cheap way that concrete is laid. First off, the major components of modern concrete are pretty uniform: sand and rock, Portland cement powder (made from cooked limestone, mostly), water, air, and sometimes ash. The cement component is what holds it all together — cements it together as it were — but it is not the majority of even the strongest concretes. The formula of cement has changed too, but the cement is not generally the problem. It doesn’t necessarily stick well to the rock or sand component of concrete (It sticks far better to itself) but it sticks well enough that spoliation, isn’t usually a problem by itself.

What causes problem is that the strength of concrete is strongly affected (decreased) by having lots of sand, aggregate and water. The concrete used in sidewalks is as cheap as possible, with lots of sand and aggregate. Highway and wall concrete has less sand and aggregate, and is stronger. Military and ship concrete has little sand, and is quite a lot stronger. The lowest grade, used in sidewalks, is M5, a term that refers to its compressive strength: 5 Mega Pascals. Pascals are European (Standard International) units of pressure and of strength. One Pascal is one Newton per square meter (Here’ a joke about Pascal units). In US (English) units, 5 MPa is 50 atm or 750 psi.

Ratios for concrete mixes of different strength.

Ratios for concrete mixes of different strength; the numbers I use are double these because these numbers don’t include water; that’s my “1”.

The ratio of dry ingredients in various concretes is shown at right. For M5, and including water, the ratio is 1 2 10 20. That is to say there is one part water, two parts cement, 10 parts sand, and 20 parts stone-aggregate (all these by weight). Added to this is 2-3% air, by volume, or nearly as much air as water. At least these are the target ratios; it sometimes happens that extra air and water are added to a concrete mix by greedy or rushed contractors. It’s sometimes done to save money, but more often because the job ran late. The more the mixer turns the more air gets added. If it turns too long there is extra air. It the job runs late, workers will have to add extra water too because the concrete starts hardening. I you see workers hosing down wet concrete as it comes from the truck, this is why. As you might expect, extra air and water decrease the strength of the product. M-10 and M-20 concrete have less sand, stone, and water as a proportion to cement. The result is 10 MPa or 20 MPa strength respectively.

A good on-site inspector is needed to keep the crew from adding too much water. Some water is needed for the polymerization (setting) of the concrete. The rest is excess, and when it evaporates, it leaves voids that are similar to the voids created by having air mix in. It is not uncommon to find 6% voids, in commercial concrete. This is to say that, after the water evaporates, the concrete contains about as much void as cement by volume. To get a sense of how much void space is in the normal concrete outside your house, go outside to a piece of old concrete (10 years old at least) on a hot, dry day, and pour out a cup of water. You will hear a hiss as the water absorbs, and you will see bubbles come out as the water goes in. It used to be common for cities to send inspectors to measuring the void content of the wet (and dry) concrete by a technique called “pycnometry” (that’s Greek for density measurement). I’ve not seen a local city do this in years, but don’t know why. An industrial pycnometer is shown below.

Pyncnometer used for concrete. I don't see these in use much any more.

Pycnometer used for concrete. I don’t see these in use much any more.

One of the main reason that concrete fails has to do with differential expansion, thermal stress, a concept I dealt with some years ago when figuring out how cold it had to be to freeze the balls off of a brass monkey. As an example of the temperature change to destroy M5, consider that the thermal expansion of cement is roughly 1 x 10-5/ °F or 1.8 x10-5/°C. This is to say that a 1 meter slab of cement that is heated or cooled by 100°F will expand or shrink by 10-3 m respectively; 100 x 1×10-5 = 10-3. This is a fairly large thermal expansion coefficient, as these things go. It would not cause stress-failure except that sand and rock have a smaller thermal expansion coefficients, about 0.6×10-5 — barely more than half the value for cement. Consider now what happens to concrete that s poured in the summer when it is 80°F out, and where the concrete heats up 100°F on setting (cement setting releases heat). Now lets come back in winter when it’s 0°F. This is a total of 100°F of temperature change. The differential expansion is 0.4 x 10-5/°F x 100°F =  4 x10-4 meter/meter = 4 x10-4 inch/inch.

The force created by this differential expansion is the elastic modulus of the cement times the relative change in expansion. The elastic modulus for typical cement is 20 GPa or, in English units, 3 million psi. This is to say that, if you had a column of cement (not concrete), one psi of force would compress it by 1/3,000,000. The differential expansion we calculated, cement vs sand and stone is 4×10-4 ; this much expansion times the elastic modulus, 3,000,000 = 1200 psi. Now look at the strength of the M-5 cement; it’s only 750 psi. When M-5 concrete is exposed to these conditions it will not survive. M-10 will fail on its own, from the temperature change, without any help needed from heavy traffic. You’d really like to see cities check the concrete, but I’ve seen little evidence that they do.

Water makes things worse, and not only because it creates voids when it evaporates. Water also messes up the polymerization reaction of the cement. Basic, fast setting cement is mostly Ca3SiO5

2Ca3SiO5 + 6 H2O –> 3Ca0SiO2•H2O +3Ca(OH)2•H2O.

The former of these, 3Ca0SiO2•H2O, forms something of a polymer. Monomer units of SiO4 are linked directly or by partially hydrated CaO linkages. Add too much water and the polymeric linkages are weakened or do not form at all. Over time the Ca(OH)2 can drain away or react with  CO2 in the air to form chalk.

Portland limestone cement strength versus curing time. Slow curing and damp helps; fast dry hurts. Carbonate formation adds little or no strength. Jehan Elsamni 2011.

Ca(OH)2 + CO2 → CaCO3 + H2O

Sorry to say, the chalk adds little or no strength, as the graph at right shows. Concrete made with too much water isn’t very strong at all, and it gets no stronger when dried in air. Hardening goes on for some weeks after pouring, and this is the reason you don’t drive on 1 too 2 day old concrete. Driving on weak concrete can cause cracks that would not form if you waited.

You might think to make better concrete by pouring concrete in the cold, but pouring in the cold makes things worse. Cold poured cement will expand the summer and the cement will detach from the sand and stone. Ideally, pouring should be in spring or fall, when the temperature is moderate, 40-60°F. Any crack that develops grows by a mechanism called Rayleigh crack growth, described here. Basically, once a crack starts, it concentrates the fracture forces, and any wiggling of the concrete makes the crack grow faster.

Based on the above, I’ve come to suspect that putting on a surface coat can (could) help strengthen old concrete, even long after it’s hardened. Mostly this would happen by filling in voids and cracks, but also by extending the polymer chains. I imagine it would be especially helpful to apply the surface coat somewhat watery on a dry day in the summer. In that case, I imagine that Ca3SiO5 and Ca(OH)2 from the surface coat will penetrate and fill the pores of the concrete below — the sales pores that hiss when you pour water on them. I imagine this would fill cracks and voids, and extend existing CaOSiO2•H2O chains. The coat should add strength, and should be attractive as well. At least that was my thought.

I should note that, while Portland cement is mostly Ca3SiO5, there is also a fair amount (25%) of Ca2SiO4. This component reacts with water to form the same calcium-silicate polymer as above, but does so at a slower rate using less water per gram. My hope was that this component would be the main one to diffuse into deep pores of the concrete, reacting there to strengthen the concrete long after surface drying had occurred.

As it happened, I had a chance to test my ideas this summer and also about 3 years ago. The city inspector came by to say the concrete flags outside my house were rough, and thus needed replacing, and that I was to pay or do it myself. Not that I understand the need for smooth concrete, quite, but that’s our fair city. I applied for a building permit to apply a surface coat, and applied it watery. I used “Quickrete” brand concrete patch, and so far it’s sticking OK. Pock-holes in the old concrete have been filled in, and so far surface is smooth. We’ll have to see if my patch lasts 10-20 years like fresh cement. Otherwise, no matter how strong the concrete becomes underneath, the city will be upset, and I’ll have to fix it. I’ve noticed that there is already some crumbling at the sides of flags, something I attribute to the extra water. It’s not a problem yet, but hope this is not the beginning of something worse. If I’m wrong here, and the whole seal-coat flakes off, I’ll be stuck replacing the flags, or continuing to re-coat just to preserve my reputation. But that’s the cost of experimentation. I tried something new, and am blogging about it in the hope that you and I benefit. “Education is what you get when you don’t get what you want.” (It’s one of my wise sayings). At the worst, I’ll have spent 90 lb of patching cement to get an education. And, I’m happy to say that some of the relatively new concrete flags that the city put in are already cracked. I attribute this to: too much sand, air, water or air (they don’t look like they have much rock): Poor oversight.

Dr. Robert E. Buxbaum. March 5, 2019. As an aside, the 664 foot Trump Tower, NY is virtually the only skyscraper in the city to be built of concrete and glass. The others are mostly steel and glass. Concrete and glass is supposed to be stiffer and quieter. The engineer overseeing the project was Barbara Res, the first woman to oversee a major, NY building project. Thought question: if you built the Trump Tower, which quality of concrete would you use, and why.

Great waves, small circles, and the spread of ideas.

Simplified wave motion, GIf by Dan Russel (maybe? I think?).

The scientific method involves looking closely at things. Sometimes we look closely for a purpose — to make a better mouse-trap, say. But sometimes it’s just to understand what’s happening: to satisfy curiosity, to understand the way the world works, or to answer a child. Both motivations bring positive results, but there is a difference in how people honor the product of these motivations. Scientific knowledge developed for curiosity is considered better; it tends to become the model for social understanding, and for art and literature. Meanwhile, science developed for a purpose is considered suspect, and often that suspicion is valid. A surprising amount of our knowledge was developed for war: for the purpose of killing people, destroying things, and occupying lands.

Waves provide a wonderful example of science exploration that was developed mostly for curiosity, and so they have become models of social understanding and culture — far more so than the atom bomb and plague work discussed previously.

Waves appear magical: You poke a pond surface with a stick, and the influence of that poke travels, as if by magic, to all corners of the pond. Apparently the initial poke set off something, and that sets off something else, and we’ve come to use this as a model for cultural ideas. Any major change in music, art, or cultural thought is described as a wave (and not as a disease). The sense of wave is  that a small push occurs, and the impact travels across a continent and across an ocean. The Gifs above and below shows how this happens for the ordinary wave — the one with a peaked top. As shown, the bits of water do not move with the wave. Instead they just circulate in a small circle. The powerful waves that crosses an ocean are composed of many small circles of water rolling in the general direction of the wave. With ideas too, I think, one person can push a second, and that second a third, each acting in his or her own circle, and a powerful transmission of ideas results. Of course, for a big wave, you need a big circle, but maybe not in cases of reflection (reflected waves can add, sometimes very destructively).

simplified wave movement

In the figures I’ve shown, you will notice that the top of the circle always moves in the same direction as the top of the wave. If the wave moves to the right, the circle is clockwise. There are also Rayleigh waves. In these, the top of the wave is not peaked, but broad, with little indents between ripples. For Rayleigh wave the motion is not circular, but elliptical, and the top of the ellipse moves in the opposite direction to that of the wave. These waves go slower than the normal waves, but they are more destructive. Most of the damage of earthquakes is by the late-arriving Rayleigh waves.

If regular waves are related to fast-moving ideas, like rock n roll, Rayleigh waves might be related to slower-traveling, counter-intuitive ideas, paradigm shifts: Religions, chaos, entropyfeminism, or communism. Rayleigh waves are mostly seen in solids, and the destructive power of counter-intuitive ideas is mostly seen in rigid societies.

Then there are also pressure waves, like sound, and wiggle waves (transverse waves). Pressure waves travel the fastest, and work in both solids and liquids. Wiggle waves travel slower (and don’t travel in liquids). Both of these involve no circles at all, but just one bit of material pushing on its neighbor. I think the economy works this way: bouncing springs, for the most part. Life is made up of all of these, and life is good. The alternative to vibration, I should mention, is status. Status is a form of death. There is a certain sort of person who longs for nothing more than an unchanging, no-conflict world: one government and one leadership. Avoid such people.

Water Conservation for Michigan – Why?

The Michigan Association of Planners is big on water conservation, joining several environmental groups to demand legislation requiring water conservation:

POLICY 4. Water Conservation: The Michigan Association of Planning supports state legislation requiring water conservation for public, and private users.

Among the classic legislation passed so far are laws requiring low flush toilets, and prohibiting high-volume shower heads as in this Seinfeld episode. I suppose I should go along: I’m running for water commissioner, and consider myself a conservationist. The problem is, I can’t see a good argument for these laws for most people here in Oakland County, or in neighboring Macomb and Wayne Counties. The water can’t run out because most users take it from the river and return it to the river, cleaned after it’s used; it’s all recycled.

Map of the main drinking-water pipes serving south-east Michigan

Map of the main drinking-water pipes serving south-east Michigan

The map above shows the clean water system for south-east Michigan. The high-population areas, the ones that are colored in the map, get their water from the Detroit River or from Lake Huron. It’s cleaned, pumped, and carried to your home along the pipes shown. Then after you’ve used the water, it travels back along another set of pipes to the water treatment plant and into the Detroit River.

Three-position shower head -- a wonderful home improvement  I got it at universal plumbing.

Three-position shower head — a wonderful home improvement. I got it at universal plumbing.

When the system is working well, the water we return to the Detroit River is cleaner than the water we took in. So why legislate against personal use? If a customer wants to enjoy a good shower, and is willing to pay for the water at 1.5¢ per gallon, who cares how much water that customer uses? I can understand education efforts, sort-of, but find it hard to push legislation like we have against a high-volume shower head. We can not run out, and the more you use, the less everyone pays per gallon. A great shower head is a great gift idea, in my opinion.

The water department does not always work well, by the way, and these problems should be solved by legislation. We give away, for $200/year, high value clean water to Nestle company and then buy it back for $100,000,000. That’s a problem. Non-flushable toilet wipes are marketed as flushable; this causes sewer blockades. Our combined sewers regularly dump contaminated water into our rivers, lakes, and basements. These problems can be solved with legislation and engineering. It’s these problems that I’m running to solve.

Robert Buxbaum, January 6, 2019. If you want to save water, either to save the earth, or because you are cheep, here are some conservation ideas that make sense (to me).

We don’t need no stinking primary clarifier

Virtually every sewage plant of Oakland County uses the activated sludge process, shown in the layout below. Raw sewage comes in, and goes through physical separation — screening, grit removal, and a first clarifier – settling tank before moving to the activated sludge oxidation reactor. The 1st clarifier, shown at left below, removes about half of the incoming organics, but it often stinks and sometimes it “pops” bubbles of fart. This is usually during periods of low flow, like at night. When the flow is slow, it arrives at the plant as a rotting smelly mess; it’s often hard to keep the bubbles of smell down.

Typical Oakland Sewage plant, activated sludge process with a primary clarifier.

Typical Oakland County Sewage treatment plant, activated sludge process with a primary clarifier.

The smell is much improved in the oxidation reactor, analyzed here, and in the 2nd clarifier, shown above at right. Following that is a filter, an ultraviolet cleanup stage, and the liquids are discharged to a local river. In Oakland county, the solids from the two clarifiers are hauled off to a farm, or buried in a landfill. Burial in a landfill is a costly waste, as I discuss here. The throughputs for most of these treatment plants is only about 2-3 million gallons of sewage per day. But Oakland county can produce 500 million gallons of sewage per day. The majority of this goes to Detroit for treatment, and sometimes the overflow is dumped rotting and smelly, in the rivers.

A few months ago, I visited the Sycamore Creek Wastewater facility outside of Cincinnati. This is an 8 million gallon per day plant that uses the “extended aeration process”, shown in the sketch below. I noticed several things I liked: the high throughput (the plant looks no bigger than our 2-3 million gallon plants) and the lack of a bad smell, primarily. The Sycamore Creek plant had an empty hole where the primary clarifier had once been. Lacking this clarifier, the screened sewage could not sit and pop. Instead it goes directly from grit removal to the oxidation reactor, a reactor that looks no bigger than in our plants. This reactor manages a four times higher throughput, I think, because of a higher concentration of cellular catalyst. Consider the following equation derived in a previous post:

ln C°/C = kV/Q.

Here, C° and C are the incoming and exit concentrations of soluble organic; k is the reaction rate, proportional to cellular concentration, V is the volume of the reactor, Q is the flow, and ln is natural log. The higher cellular concentration in the extended aeration plant results in an increased reaction rate, k. The higher the value of k, the higher the allowed flow, Q, per reactor volume, V.

The single clarifier at the end of the Sycamore Creek plant does not look particularly big. My sense is that it deals with a lot more sludge and flow than is seen in our 2nd clarifiers because (I imaging) the sludge is higher density, thus faster settling. I expect that, without the 1 clarifier, there is extra iron and sulfate in the sludge, and more large particles too. In our plants, a lot of these things are removed in the primary clarifier. Sludge density is also increased, I think, because the Cincinnati plant recycle a greater percentage of the sludge (I list it as 90% in the diagram). Extra iron in the reactor also helps to remove phosphates from the water effluent that flows back to the river, an important pollution concern. Iron phosphates are insoluble, and thus leave with the sludge. In Oakland county’s activated sludge plants, it is typical to add iron to the reactor or clarifier. In Cincinnati’s extended aeration plant, I’m told, iron addition is generally not needed.

Typical Oakland Sewage plant, activated sludge process with a primary clarifier.

Cincinnati sewage treatment plant, extended aeration process with no primary clarifier.

The extended aeration part of the above process refers to the secondary sludge oxidizer, the continuously stirred tank reactor, or CSTR shown at lower right above. The “CSTR” is about 1/5 the volume of the main oxidation reactor and about the size of a clarifier. Oxidation in the CSTR compliments that in the main oxidizer removing organics, making bio-polymer, and improving (I think) the quality of the sludge that goes to the farms. Oxidation in the CSTR reduces the amount of sludge that goes to the farms. The sludge that does go, is  less-toxic and more concentrated in organics and minerals. I’m not sure if the CSTR product is as good as the product from an anaerobic digester, or if the CSTR is cheaper to operate, but it looks cheaper since there is no roof, and no (or minimal) heating. This secondary oxidizer is very efficient at removing organics because the cellular catalyst concentration is very high – much higher than in the main oxidizer.

During periods of high load, early morning, the CSTR seems to serve as a holding tank so that sludge does not build up in the clarifier. Too much sludge in the clarifier can start to rot, and ruin the effluent quality. The way you tell if there is too much sludge, by the way, is through a device called the “sludge judge.” I love that name. The Cincinnati plant used a centrifugal drier; none of our plants do. The Cincinnati plant had gap the bubble spots of the main oxidizer. This is good for denitrification, I’m told, an important process that I discuss elsewhere.

The liquid output of their clarifier (or ours) is not pure enough to be sent directly to the river. In this plant, the near-pure water from the clarifier is sent to a trickling filter, a bed of sand and anthracite that removes colloidal remnants. Some of our plants do the same. I suspect that the large surface area in this filter is also home to some catalysis: last stage oxidation of remaining bio-organics. On a regular basis, the filter bed is reverse-flushed to remove cellular buildup, slime, and send it to the beginning of the process. The trickling filter output is then sent to an ultraviolet, bacteria-killing step before being released to the rivers. All in all, I suspect that an extended aeration process like this is worth looking into for Oakland County, especially for our North Pontiac sewage treatment facility. That plant is particularly bad smelling, and clearly too small to treat all its sewage. Perhaps we can increase the throughput and decrease the smell at a minimal cost.

Presidential drinks, smokes, and other vices

I’d written about presidential desks so now presidential drinking and related vices. The US colonials were hard drinkers, and their leaders lead on this front too. The colonials who fought at Lexington and Concord loaded up at Bradford’s Tavern before greeting the British. Meanwhile, safe in Philadelphia, each of the authors of the declaration of Independence drank, on average, two pint tankards of rum per day, likely mixed with water, a mixture called “grog,” or mixed with apple cider, a mix called “the stone fence.”

Washington's bar bill for 55 men.

Washington’s bar bill for 55 men; food was less than 1/4 of the bill, both for the officers and the servants. Note the “Segars” and broken crockery.

The standard of drinking for officers in the colonial army can be seen from the bill for the farewell dinner (right) held at City Tavern in New York. The average man drank more than two bottles of wine, about a quarter bottle of old stock (whiskey)  bottle of beer, porter or cider, and 1/2 bowl of punch. There is also a cost for “segars” and for broken cookery. The servants drank almost as much but not quite. George Washington was considered a very modest drinker in the crowd, avoiding rum mostly, and sticking to Madera wine or dark, “Philadelphia” porter, typically mixed with molasses. He smoked a pipe too, but didn’t have a mistress nor did he fight in any duels; a model for presidents to come. When Washington retired from the presidency, he become the premier distiller in the USA, making thousands of barrels of rye whiskey per year. A good man and a good president, IMHO.

John Adams considered himself a temperance man, and complained of Washington’s lack of refinement. He didn’t smoke at all, and drank only one tankard of hard cider to start the day, followed by beer, Madera and diluted rum (grog). He was priggish and disliked. He also started the pseudo war with France, spent massively to pay off the Barbary pirates, insulted most everyone, and passed the single worst law ever in US history, Our worst president, IMHO, but at least he didn’t overspend.

According to "The Balance, and Columbian Repository" 1806, "A cock tail is a stimulating liquor composed of spirits of any kind, sugar, water and bitters. It is supposed to be an excellent electioneering potion inasmuch as it renders the heart stout and bold, at the same time that it fuddles the head. It is said also, to be of great use to a democratic candidate: because, a person having swallowed a glass of it, is ready to swallow any thing else."

According to “The Balance, and Columbian Repository” May 15, 1806, “– Cock tail then is a stimulating liquor… an excellent electioneering potion inasmuch as it renders the heart stout and bold, at the same time that it fuddles the head… of great use to a democratic candidate: because, a person having swallowed a glass of it, is ready to swallow any thing else.”

Jefferson was a spendthrift who  spent $16,500 in the money of the day (well over $1 million today) on French wine; $11,000 for his time in the Whitehouse and $5,000 for the ministry in Paris. His wine habits, along with his book and furniture buying, led him to be bankrupt twice. The first time, he was bailed out by congress, the second time (at his death) his slaves and property were sold off to pay debts, including his red-haired, slave children. Not a good man, but a good president. He ended Adam’s the pseudo-war with France, defeated the Barbary pirates, and doubled the size of America through the Louisiana purchase.

James Madison, like Jefferson preferred French wine, mostly Champaign, but he didn’t drink much of it, according to the standard of the day. He said that, if he drank any more than 3 or so glasses or he’d wake up with a headache. He also smoked ‘seegars’ until his death at 85: a good man but a poor president. Who would declare war on the most powerful nation on earth without first preparing his army or navy? Dolly Madison is considered the first of the “First Ladies,” for her hostess prowess.

Monroe liked French Champaign and Burgundy. He was the last of the “gentleman presidents; liked as a man and as a president, doing little that was controversial, except perhaps stating the Monroe Doctrine — US control of the Caribbean. He oversaw an “era of good feelings,” where the US grew and wounds healed.

John Quincy Adams was as obnoxious and disliked like his father, “the bitter branch of the bitter tree.” He was a wine-snob who claimed to have conducted a blind taste test with 14 kinds of Madeira and correctly identified 11 of them. After his one-term as president he returned to congress where his last act was to vote against admitting Texas to the union. At least 17 male-line Adams’s have graduated from Harvard; few are remembered fondly.

Andrew Jackson was not a gentleman. He drank whiskey — home made — and smoked cigars along with his wife. He fought about 20 duels, served whiskey proudly to all his guests, and removed the requirement of land to vote. He was a drinker of coffee too, pairing it with cigars, and is reported to have said, “Doctor, I can do anything you think proper, except give up coffee and tobacco.” One famous duel was with his lawyer, Thomas Hart Benton. Benton shot him twice, and they become friends and allies for life. Jackson added the first running water in the white house. The source was soon contaminated by human waste but I can’t complain. We have similar problems in Oakland county today. He also paid down the national debt, leaving Van Buren with a surplus for the first and only time in America. I consider Jackson an excellent president, but have not decided about him as a man.

Van Buren was a heavy drinker, a pipe smoker, a corrupt Tammany man, and a bit of a spendthrift (“Martin Van Ruin”)  He is the only US president to grow up speaking Dutch, not English, and his favored drink was Schiedam, a blue-colored gin favored by New York’s Dutch. Most people could not stand Schiedam, and it led Van Buren to be called “Blue whiskey Van.” Gin is an acquired taste — one that several later presidents would acquire. My guess is that Schiedam is the reason that some modern gins come in blue bottles. Van Buren accomplished nothing of note as president.

William Henry Harrison smoked a pipe and drank nothing harder than cider. Modest drinking differentiated him from hard-drinking Van Buren. His campaign song — Tippicanoe and Tyler too — includes the line “Van is a used-up man”, but modest drinking may have killed him too. He likely died of infected water in the Whitehouse —  something that could have been cured by a bit of whiskey mixed into the infected water. (I’m running for water commissioner my campaign: clean water at an appropriate pressure for fire-fighting.
Explosion_aboard_USS_Princeton

John Tyler, Harrison’s VP, drank and smoked cigars. He kept two kegs of “Lieutenant Richardson’s whiskey” on hand, and Champaign for state dinners. He was a compromiser, who missed dying in an explosion on the USS Princeton because he’d stopped off for a drink. Most of the rest of his cabinet were not so lucky. He was rejected for re-election in favor of Polk, who promised to admit Texas.

James K. Polk was a modest drinker who favored the occasional wine or brandy. He survived his single term in the Whitehouse to die 105 days after leaving the Whitehouse of gastro-enteritis caused by infected water or fruit. A bit of whiskey might have helped. By admitting Texas, Polk started the Mexican – American War. This expanded the US further, all the way to California. I rather like Polk, but most historians do not.

Zachary Tayler, a Whig, “old rough and ready” had been a whiskey man in the army but never drank as president and rarely smoked in the white house. He died 1 1/2 years after taking office, likely killed by the bad water and lack of alcohol. Tayler was against all forms of secession and against the fugitive slave compromise that Clay. I like Tayler and agree with him.

Millard Fillmore was Tayler’s vice president and another non-smoker, he drank Madera wine as had some early presidents. Always concerned with his health, and is said to have installed the first bathtub, installing with it with copper and brass pipes. I suspect that the copper pipes saved Fillmore from DC’s bad water as copper is a fine anti-microbial. Though opposed to slavery, Fillmore signed the fugitive slave compromise that brought California into the union as a free state. The civil war is sometimes blamed on Fillmore, unfairly I think. It could not have been stopped. He died at the ripe age of 74, long after having left the Whitehouse.

Franklin Pierce, a Democrat and alcoholic, was “the hero of many a well-fought bottle”. Not a bad president, in my opinion. He saw the inevitable civil war coming and could not stop it, His wife lost her mind and his children all died. The last one, Benny, by beheading in front of him when a train Pierce and his wife were about to board broke its axle and slid down a hill. Pierce added the Gadson purchase, made the civil service less corrupt, made treaties with Britain and opened Japan. He too is blamed for the civil war by current historians as if they could have done better. He died of cirrhosis at 65, 13 years after leaving office.

James Buchanan, another Democrat was likely our only homosexual president. Buchanan was a life-long bachelor who drank quite a lot. His favorite was originally “Old Monongahela” but switched to J. Baer “finer than the best Monongahela,” buying ten gallons of J.Baer (rye) per week, direct from the distillery. “The Madeira and sherry that he has consumed would fill more than one old cellar, and the rye whiskey that he has ‘punished’ would make Jacob Baer’s heart glad.” Like Pierce, he is blamed by historians for not saving the union, as if this were an easy job that anyone could have done. Buchanan had no problem with the White House water, but was heart-broken when his housemate, William King left to become minister to France.

Lincoln didn’t drink or chew tobacco, nor did he have mistresses, or apparent trouble with the water. He was depressive though, told wonderful stories, some of them true, smoked a pipe, and once almost fought a duel with swords that broken up by the wives of the duelers. A good man and a great president. His son, Robert was present at his murder, and at two other presidential shootings.

Andrew Johnson drank and smoked occasionally, but had a low tolerance. Johnson added Alaska by purchase (Seward’s folly) but is not liked or respected by historians. I consider this unfair: he compares unfavorably to Lincoln, but don’t we all, and he could not smooth reconstruction, a near impossible task. His main impeachment crime was bombastic speech, by the way, a vice he shares with Andrew Jackson and Donald Trump. Like Buchanan and Pierce, I consider him a good president doing a near-impossible job.

Ulysses S. Grant was a Republican, a heavy cigar smoker, but a light drinker. Grant smoked as many as 20 cigars per day (a Grant cigar is 5″ long by 42 ring), but drank only brandy for his health, and not too much of that. Later in life he drank a mixture of wine and cocaine for throat pain from cancer. This stuff, a favorite of Pope Leo, was the inspiration for Coca-Cola. Grant’s campaign song, “Grant Grant Grant” specifically mentions his opposition to the KKK. He did a good job with reconstruction though the Democrats hated him for it. They mocked him as a drunk and worse: “I smoke my weed and drink my gin, playing with the people’s tin.” Grant wrote a great autobiography with the help of Mark Twain.

Hayes, a Republican, didn’t drink at all and opposed others’ drinking. Elected in 1876, he banned liquor of all sorts in the white house, and his wife was known as “Lemonade Lucy.” Hayes is criticized for corruption and for reducing the burdens of reconstruction. His opponent, Tammany Tilden, was at least as corrupt, and a stronger opponent of reconstruction.

Garfield was a beer man who “drank little else.” He tried to reform the civil service, but died from a gunshot and doctor-caused infection shortly after taking office. If his wound had been disinfected he would have probably lived. That’s what Roosevelt did when he was shot.

Chet Arthur, a cigar smoker and enthusiastic drinker, was Garfield’s vice president. When pressured for a no-liquor policy in the White House, he responded: “Madam, I may be the president of the United States, but what I do with my private life is my own damned business!” Arthur liked late night dining that he would finish with Champagne and a cigar. Though his background was in corrupt civil service, as president he did his best to remove this corruption from the civil service. A good president, IMHO.

Grover Cleveland was a cigar and beer man. Weighing 250 lbs, he was known as ‘Big Steve’ or ‘Uncle Jumbo,” In the white house, he limited himself to a gallon of beer a night. That is he drank four tankards of 1 liter each. He’d drank more before becoming mayor of Baltimore. He fathered a child at that time by seduction, perhaps date rape, of Maria Halpin, a 38-year-old sales clerk. She named the child Oscar Folsom Cleveland, the two last names suggesting she was not sure of the father. Cleveland and Folsom had Maria sent to an insane asylum (she was not crazy) and had Oscar was sent to an orphanage. In the end, Maria was freed and Oscar was adopted by Dr. King a trustee of the orphanage. None of this horrible behavior stopped Cleveland from becoming mayor and president. Cleveland married the 21-year-old daughter of his friend, Folsom. Rutherford Hayes was revolted by it all: “Cleveland … is a brute with women.” Cleveland smoked foot-long, ‘supercoronas’ that he received as gifts, using these cigars to influence people and conversations, similar to Churchill. Not a good man, nor a particularly good president, IMHO. Baby Ruth candy was not named after Cleveland’s daughter Ruth, but after the baseball player. IMHO, the candy company claimed otherwise only to avoid paying royalties. Cleveland is remembered fondly by historians, but not by me. I read two of his books.

Benjamin Harrison didn’t drink, but he did smoke cigars and he allowed liquor in the white house though prohibition was a growing issue. He annexed Hawaii, improved the navy, and replaced the “spoils system” for civil service jobs with a merit system. He also tried unsuccessfully to provide voting rights for African-Americans. The move failed in the senate. Cleveland defeated him in his run for a second term by pointing out that tariffs were too high. A tariff battle would dominate the Democrat / Republican split for a generation, and has recently reappeared. Modern historians don’t much like Harrison as he didn’t succeed in providing civil rights, as if that were an easy battle.

mckinleyMcKinley drank scotch whiskey — Dewar’s, a brand provided by Andrew Carnegie, and he smoked several cigars per day. He would not smoke in public though there is artwork, as at right, and the comment that “one never saw McKinley without a cigar in his mouth except at meals or when asleep.’. The McKinley delight is a variant of the Manhattan made with 3 oz of rye whiskey (at least 100 proof), 1 oz. sweet vermouth, 2 dashes of cherry brandy, and 1 dash absinthe. McKinley was shot and started to recover before dying from doctor-caused infection (he used the same doctor the Garfield had).

Theodore Roosevelt, was McKinley’s VP, and is one of the most beloved and colorful presidents in US history. He smoked cigars starting when he was 8, but swore off them later. He drank modestly, a version of the mint julep and served it to anyone who’d play tennis with him. Roosevelt’s version used rye plus brandy instead of Bourbon: 2-3 oz of rye whiskey, 10 to 12 fresh mint leaves “muddled” with a splash of water, a sugar cube, ¼ oz. of brandy and a sprig or two of mint as a garnish. The fresh mint was grown on the Whitehouse grounds. T. Roosevelt wrote some 30 books (I’ve read four or five) they are all wonderful. Roosevelt did daring things, like ride a moose, and survived being shot by leaving the bullet where is was; here’s a photo and essay. I don’t understand why so many US presidents drank rye and not Bourbon (Bourbon — corn whiskey — had been invented in the late 1700s and is tastier, IMHO). One of TR’s most famous speeches, “the man in the arena”, was given at the Sorbonne 1910. He claimed that being a critic was not much of an achievement.

William H. Taft smoked cigars and like Champaign, but rarely drank; he was on a perpetual diet. He tried to continue Roosevelt’s programs, but got little done. Still the country did well. He’s most remembered for the “7th inning stretch” break near the end of every baseball game.

Woodrow Wilson drank scotch and smoked cigarettes. His campaign slogan, “Wilson that’s all” was a whiskey slogan. Prohibition began during Wilson’s time in office: it was supposed to help women, but did not. It brought corruption and misery. Here’s an anti-alcohol song of the day: “behind those swinging doors.”

Harding's humidor - a massive thing

Harding’s humidor – a massive thing

Despite prohibition, Harding had poker nights twice a week where he smoked cigars, and the whiskey flowed freely. He also had at least 7 mistresses; he got two of them pregnant. Not a good man or a particularly good president. He died in office, perhaps killed by his wife or by his lifestyle.

Calvin Coolidge was Harding’s VP. Coolidge smoked cigars and drank sweet, Tokay wine. As president he cut spending and taxes, paid down the debt, and did not say much. Much of the detail work was done by his secretary of commerce, Herbert Hoover. Here is the Coolidge cooler: 1.5 oz. of Vermont White vodka, ½ oz. of American whiskey, 2 oz. of orange juice, Club soda. A good man and a good president, IMHO.

H. Hoover liked good wine and dry gin-martinis, but didn’t drink either in the white house as he respected prohibits as his predecessors did not. Also, his wife poured out his extensive wine collection. He is blamed for the great depression, unfairly I think. The depression hit all other industrial countries at the same time (most economies revered before ours did). Hoover’s dying request, at 80, was for a good, dry martini. He is the first gin man since Van Buren, but not the last.

FDR and Churchill

FDR and Churchill. They drank Champaign and whiskey.

FDR was the first gentleman president since Monroe. He smoked 2 packs of cigarettes per day and drank gin martinis, very dry. Also, “old-fashioneds”, and daiquiris mixed with orange juice (a rum sizzle it’s called). The old-fashioned is made of whiskey, sugar, water, and bitters. FDR spent his last day with one of his mistresses (his wife had a mistress too) and his last words were to recount how much Churchill drank. FDR also took cocaine. It was a fairly normal medication at the time. He took some before giving the famous speech “December 7, 1941….” I question the harsh sentences we now give to users of this drug.

Truman was not a gentleman, but a fine president, IMHO. He swore with abandon, was a bourbon man, and liked to play poker with his buddies late into the night. He liked to include a shot of bourbon with his breakfast before his morning walk, took another shot “for freedom” when he entered the senate, drank bourbon with his poker buddies, and sometimes had bourbon with dinner. Truman’s buddies and colleagues were impressed that he was always up early though, and ready for work. He worked hard, didn’t smoke, and was true to his wife. He lived a long life, dying at 88 in 1972.

Eisenhower typically drank scotch with ice.

Eisenhower drank scotch over ice.

Eisenhower liked scotch, golf, smoking cigarettes and cigars, and entertaining. He had a mistress (his driver) and mostly entertained business men who he would sound out for advice on the issues of the day. He limited himself to only one drink a day or a bit of a second because of his health. It’s a good standard. Eisenhower was one of the first presidents to have a secret-service nickname, “scorecard” because of his love of golf. Before him, only Wilson played more golf.

John F. Kennedy had many mistresses, and was the last to smoke cigars in public while president. He drank classy drinks like Daiquiris, Bloody Marys and Heineken beer, imported from Holland. The Daiquiri is made of rum, lime, sugar, and water. Kennedy lived on amphetamines from “Dr Feelgood,” his personal physician. He is supposed to have tried LSD and marijuana too, His secret service nickname was “Lancer”, a reference to Lancelot, the philandering knight of Camelot fame. A famous story of Kennedy is that, right before signing the embargo of Cuba, he instructed an assistant to buy up every Cuban cigar he could find. He bought over 1000 and then signed the embargo. Not one of my favorite presidents. Jacquline Kennedy smoked like a train, Salems.

Screen Shot 2018-09-13 at 10.58.11 PMLBJ was a cigarette smoker and a heavy drinker who’s responsible for “Bourbon and Branch” becoming the semi-official drink of Texans. Branch water is just another name for water, BTW. He also drank scotch: Cutty Sark or Teachers, and used his ability to hold liquor in negotiations. He’d greet congressional opponent with two bottles, requesting that they finish them before talking. After that, they were pliable, especially since, sometimes he’d have his diluted. A very good president, IMHO: he was able to implement civil right law that had eluded a century of presidents.
nixon-cigars

Nixon is hated, unfairly I think. He liked fine wine and fruity mixed drinks like Mai Tais, but served mediocre wine to guests. He was an ex-smoker of cigarettes – switched to cigars by the time he was president, but smoking them in private, and handing out bubble gum cigars as a campaign prop. Mai Tais are wonderful drinks, the recipe is 60 ml Jamaican and Martinique Rums, 25 ml Fresh Lime Juice, 15 ml Orange Curaçao, 15 ml Orgeat, 3-4 Crushed Ice Cubes. Nixon ended the Vietnam war and began good relations with Russia and China. I also started the EPA, and is the first president to deal well with the Indians, dividing Alaska land nicely. Watergate was his downfall, helped in part by Deep Throat, the second in command of the FBI who was bypassed for a promotion.

Gerald Ford smoked a pipe in public, and liked gin martinis during lunch or with friends, or gin and tonics in the summer. He didn’t drink to excess, and most people liked him. He’s criticized for thinking Russia was an enemy, and for not stopping inflation, as if anyone else could have done it.

Carter didn’t drink or smoke, and was critical of those who did, a possible swipe at Ford. When he had an arms summit with the Soviets, Carter toasted the soviets with a small glass of white wine. He’s the least favorite president of my life-time; he backed tyrants and thought that deficit spending would cure the economy. He got nothing more than foreign policy abuse and stag-flation (inflationary recession). Carter’s secret service name was “Deacon,” because of his church leanings. 114000446

Reagan liked California wine and the Orange Blossom Special: 1 oz. (or slightly less) vodka, 1 oz. of either grenadine or sweet vermouth, 2 oz. fresh orange juice, served over ice. Reagan smoked before becoming president, and ate jelly beans as a way of quitting. They became his signature dish. As president, Reagan was a deficit spender but he got better results than Carter had perhaps because he achieved his deficit by lowering taxes.

George HW Bush drank beer or vodka martinis in moderation, and smoked the occasional cigar. He may have had a mistress, too. A vodka martini is a mix of vodka and dry vermouth mixed in at about 4 to 1. I find it flavorless. He liked (likes) sailing and skydiving. Of the recent presidents, he is the fondest remembered by the white house staff. The soviet union collapsed in his day. A good president and a good man.

Screen Shot 2018-09-13 at 10.58.40 PMBill Clinton smoked pot in college and after, though he claims to have not inhaled. In the white house he smoked cigars, but not in public, and liked an English drink called a snake-bite: 50% beer, 50% hard cider. His secret service name was “eagle,” perhaps because of his eagle eye for women. Several women claimed that he’d pressured them into sex. Clinton denied all charges until one, a 22-year-old intern, turned up with the stained dress. He was a good president but a lousy person. His cigar of choice, the Gurkha Grand Reserve, is slightly longer and wider than the Grant cigar, 6 inches by 50 ring.

George W. Bush had been a heavy drinker in college but completely swore off by the time he was president. When his father had been president, his secret service name had been “Tumbler,” a reference to his drinking and its ill-effects. He requested a different nickname as president, Timberwolf. It sounds vaguely like Tumbler. His main presidential accomplishment was the war on terror, such as it is.

Obama, like Clinton, smoked pot in his youth. He switched to beer and cigarettes in the White house but doesn’t do either in public. The picture at right has him holding the glass. His secret service name is “Renegade,” and his main achievement, seems to have been a close rapport with the countries of Islam. While I can’t say that pot helped either of these men, it does not seem to have hurt them, or society. Thus, I can not favor harsh sentencesusa-whitehouse-beer-1

Trump does not drink or smoke. He has had some affairs before becoming president, but they seem to have been consensual, and he seems to have stopped by the time he entered the Whitehouse. Trump’s church leaning is positivist, and his secret service nickname is “Mogul.” He seems committed to tariffs as a way to restart the economy and as a way to bring down the debt. I wish him success.

It is not clear who is in charge when the president is drunk, nor is the law clear about presidential smoking in the Whitehouse: It is both a public building and a private residence

Robert E. Buxbaum, October 18, 2018. As a side note: The 23rd Prime Minister of Australia, Bob Hawke (1954) held the Guinness Record for fast beer drinking: 2.5 pints in under 11 seconds !
