July 13, 1916: Required to Use Lead Pipes and Polio Connection to Clean Streets

July 13, 1916: Municipal Journal articles.

Enforce Use of Lead Service Pipes. “Philadelphia, Pa.-To preserve the water supply and to help keep the streets of the city in proper condition, chief Carlton T. Davis of the bureau of water has announced that all private pipe carrying water from the public mains in the streets to buildings must be of lead from the main to the stop at the curb. The issuance of the order is possible because of the enactment of a recent ordinance by councils. At present, according to Chief Davis, about two thousand service pipes develop leaks under the paved roadways each year. This means that the water bureau loses water, the householder is subject to annoyance and the public is inconvenienced by the digging up of the streets. The bulk of service pipe leaks are caused by the use of improper material which is quickly corroded. There are more than 350,000 service pipes in use. A great many of these are of lead and give no trouble. The ordinance just passed gives the chief of the bureau of water the power to enforce the use of proper pipes.”

Commentary: I was unaware of such an ordinance in Philadelphia. I have found that dozens of other cities had similar ordinances. I have been told that the State of Pennsylvania required lead service lines early in the 20th century. In 1897, Flint, Michigan passed an ordinance requiring the installation of lead service lines. What a calamity for drinking water consumers. We are reaping the whirlwind of such decisions many years later. The graphic above shows the impact of lead exposure (paint and water) on children’s blood lead levels in 20 Pennsylvania cities (taken from a 2014 report).

Infantile Paralysis and Clean Streets. “Children of all classes have been leaving New York by the tens of thousands during the past week to escape the dreaded infantile paralysis, which has already attacked considerably more than a thousand of them and carried off about quarter of a thousand to date. These known facts are alarming enough, but probably what gives the exodus almost the nature of a panic is the unknown-the fact that no one understands how the disease is communicated from one to another. The germ is believed to enter through the noze [sic] or mouth or both; but how it is carried is a matter of surmise. Furs and furry animals, flies, the sneezing of human beings and even contact with them are considered to be possible causes.

It is noticed that most of the cases are found amid surroundings that are below the average in cleanliness, and therefore many suspect that dirt is in some way connected with the origin of the disease. As a result, housewives are being arrested and fined by the hundred for violations of city ordinances relative to uncovered garbage cans and other collections of putrescible matters, for they rather than the street cleaning and refuse collection forces are to blame for these conditions, although these forces are being increased in number and stirred to greater activity and thoroughness; the aim being to get and keep the city as clean as possible.

Commentary: While this article is not about water directly, it tells a lot about how society was dealing with the unknown during this period. If anyone doubted that the miasma theory of disease (bad smells from decaying organic material makes people sick) was still alive and well in 1916, all they have to do is read this article. While passing mention is given to the germ causing the disease, the author falls back onto filth and dirt being the ultimate breeding place for such germs—just as in the 19th century. Parents must have been terrified that such an epidemic of unknown cause was taking away their children.

April 25, 2014: Switch to Flint River Water Supply; 1926: New York Harbor a Menace

April 25, 2014: Switch to Flint River Water Supply, Flint, MI. An article published online memorialized the change earlier that day from treated water from Detroit, Michigan, to the raw water supply of the Flint River and the activation of the Flint Water Plant. The photo from that article reproduced above shows local and state officials toasting each other with water from the Flint plant. I am certain that most of them would be happy to have their images removed from that and similar photographs.

About a month after the change, residents of Flint began to complain about discolored water and odors from the new water supply. The water coming out of city taps was orange, red, yellow and brown. City and State officials tried to assure Flint citizens that the water was safe to drink even after repeated failures of primary drinking water regulations: Total Coliform Rule and the trihalomethane regulation. But the worst was yet to come.

Once the water from the Flint River was demonstrated to be more corrosive to iron and steel than water from Detroit, someone in the water department, treatment plant staff, City administration or Michigan Department of Environmental Quality (MDEQ, drinking water regulatory agency) should have asked the question, “What about corrosion of the 15,000 lead service lines serving water to homes in the City?”

Some stories about what happened in Flint state that the USEPA asked MDEQ if optimized treatment was being applied to prevent corrosion of lead service lines (LSLs). The MDEQ representative assured the USEPA that everything was just fine.

What we now know is that the treated Flint River water was highly corrosive to lead and levels greater than 10,000 ug/L have been found in some home samples. Hundreds of samples have been found to contain lead above the 15 ug/L State and federal action level. Young children who are most susceptible to the toxic effects of lead were exposed at high concentrations, which ultimately showed up as elevated blood lead levels in thousands of children.

It took the persistence of one mother in town, a smart, courageous doctor and an activist engineering professor to blow the whistle and get everyone to start paying attention to a public health emergency. Citizens of Flint owe a great deal to LeeAnne Walters, Dr. Mona Hanna-Attisha and Marc Edwards. Miguel Del Toral of the USEPA did everything that he could to ring alarm bells once he understood what was happening. Later reporting by Rachel Maddow of MSNBC brought the crisis to national attention and helped start a national discussion of the solutions needed.

Extremely high lead levels are being reported in some Flint homes many months after the shift back to Detroit water with phosphate treatment. Why is that happening? The interior surfaces of lead pipe in the Flint service area have been badly disrupted and phosphate treatment is not fixing the problem. Flint citizens should also be highly suspicious of lead results from first flush samples, which are mandated by the Lead and Copper Rule. Research has now shown that spikes of extremely high lead concentrations do not occur until more water is flushed through the system and the water that has been stagnating in lead pipes overnight is sampled and analyzed.

Here are a few questions with my best efforts to answer them.

Where did the LSLs in Flint come from and why were they installed? I found an 1897 City of Flint Ordinance that required the use of lead pipe to connect water mains to homes. I have found dozens and there must be hundreds of ordinances for other cities like this in the literature. Lead was the preferred material because other materials such as iron and steel pipes corroded away. Ironically, lead was considered a more durable material for service lines. Copper and plastic pipes were not commercially available until much later.

Why do local officials claim that water is safe to drink when it looks like orange Kool-Aid, smells like rotten eggs and tastes like sucking on a rusty nail? I have seen statements like this from city and water utility officials across the U.S. They should know by now that stating something that is clearly false to the people experiencing the delivery of bad water destroys the utility’s credibility and makes everyone angry. The only possible response is: “The water is disgusting, and even though it meets all health standards, it does not meet our standards. We are sorry. We are going to find out why this is happening and we are going to fix it.”

How in the world could this have happened? Who is responsible? Governor Rick Snyder likes to say that it happened because of a failure of government at all levels. For once, I agree with him. However, it appears to me that he says this as a way to dilute the responsibility of his administration, his state-appointed emergency manager and the state regulatory agency, the MDEQ. If the state agencies had been focused on protecting public health and not saving a few dollars, the lead poisoning disaster in Flint would never have happened. But City officials, water department personnel and the consultant who made recommendations for treatment plant upgrades also deserve some of the blame. If one person or a group of these people had stood up and raised holy hell and demanded corrosion testing of the new water supply, the crisis would have been avoided. There are lessons to learn from this disaster for everyone who is involved in serving drinking water in this country.

What about LSLs? Should they be replaced? Yes. NOW. A big mistake was made in 1991 with the adoption of the Lead and Copper Rule that did not require the replacement of all LSLs in the U.S. Also, the allowance of partial replacement of LSLs made lead exposure of the public far worse. Everyone involved in drinking water and public health should demand that the federal Lead and Copper Rule Long-Term Revisions include an accelerated schedule for replacing LSLs. Also, we should not get confused about who foots the bill. Society made the decision in the 19th and 20th centuries to use lead pipe. The homeowners and utility personnel who installed lead pipes are long dead. The total cost for LSL replacement should be paid for by utilities (with cost recovery from increased water rates) with some help from state and federal governments to seed the process and get it done. Society caused the problem and it is up to all of us to fix it. There are 6.1 million LSLs in this country and they need to be ripped out and completely replaced without delay.

April 25, 1926: New York Times headline—Harbor Sewage Called a Menace to Health. “State Legislature Urged to Take Action to Halt Pollution of New York Waters — Many Cities Pour Their Raw Waste Into the Bay. A report just submitted to the Legislature of New York urges drastic action to protect the City of New York against the menace to health arising from the pollution of the harbor and near-by bathing beaches, not only by New York but by other cities and States. Dr. George W. Soper who was Director of the Metropolitan Sewerage Commission stated that every day, 940 million gallons of sewage per day were poured into the harbor every day. He called the situation a ‘direct offense upon the sense of decency…a constant menace to health.’”

August 31, 1918: Service Line Materials, Lead is Everywhere

0831 Service line materials 1August 31, 1918: Municipal Journal article. Selection of Material for Service Pipes. “Service connections generally give more trouble to the superintendent than any other part of the water works system. This trouble is of two kinds, one being the deterioration of the quality of the water, the other consisting of leaks and stoppages. To minimize these troubles, the selection and laying of service pipes and the appurtenances combined with them should receive the most careful consideration of the superintendent….

About a year ago a committee of the New England Water Works Association collected some statistics about service pipe, mostly from New England States. These showed that 22 cities had abandoned the use of uncoated iron or steel pipe, 11 of them adopting galvanized, 4 adopting lead, 3 lead-lined, and 4 cement-lined. Seventeen had changed from galvanized to other kinds, 7 of these to lead, 7 to lead-lined, 2 to cement-lined, and 1 to enameled. Six had abandoned lead pipe, 4 of them for galvanized and 2 for cement-lined. Eight had abandoned lead-lined pipe, 5 for galvanized, 2 for cement-lined and 1 for uncoated iron or steel. Twenty-seven had abandoned cement-lined, 16 for galvanized, 6 for lead and 5 for lead-lined. The changes from plain ungalvanized pipes were made almost entirely on account of rust. Changes from lead pipes were largely on account of the possibility of lead poisoning, although in some cases it was on account of expense or because the pipes did not have sufficient strength. Lead-lined pipe was abandoned on account of lead poisoning and trouble from bursting and because of the difficulty of making joints that will not corrode.

Statistics collected by Municipal Journal in 1915 showed that, of 421 cities reporting 136 used wrought pipe exclusively and 130 for a part of their services: 144 used lead pipe exclusively and 130 for a part of the services; 4 used lead-lined pipe exclusively and 10 for part of the services: 1 used cement-lined pipe exclusively and 21 for part of the services; 1 used brass exclusively and 1 for part of the services, and 2 used tin-lined in part. Of those using lead for part of the services, 11 used it under paved streets, most of them using wrought pipe elsewhere. Lead-lined pipe appeared to be used largely and cement-lined exclusively in New England. Massachusetts was the most catholic using every kind of pipe reported.”

Commentary: From this article and the one published yesterday (August 30), it is clear that water system managers and operators knew the dangers of lead pipe in the 19th and early 20th century. The fact that it was still widely used in some cities into the 1980s and 1990s is astonishing on many levels. Of course, Washington, DC remains the poster child for how not to deal with a lead service line problem. The previous sentence was written before the disaster in Flint, Michigan was discovered and publicized. Everyone in the U.S. should now be well educated on the dangers of lead service lines and exposure of children to lead in water.
