MILWAUKEE — Top Milwaukee and state officials agreed Wednesday that Wisconsin must move as quickly as possible to replace all of the estimated 176,000 lead pipes providing drinking water to homes and businesses in the state, with Department of Natural Resources Secretary Cathy Stepp declaring, “If it costs a lot of money to do that, then it costs a lot of money to do that.”
The DNR estimates it could cost between $3,000 and $5,000 for just the homeowner’s portion to replace each lead service line; no statewide estimate was available Wednesday for how much water utilities could spend. The Milwaukee Water Works has estimated that replacing that city’s 70,000 lead service lines would cost between $511 million and $756 million.
Madison already replaced all 8,000 of its lead pipes over 11 years, at a cost of $15.5 million.
Virginia Tech University professor Marc Edwards, who led the effort to test lead-contaminated drinking water in Flint, Michigan, told about 250 people attending a symposium at Marquette University that “No one that has a lead pipe, I don’t feel, can ethically ever be told their water is safe to drink.”
The discussion also featured Milwaukee NAACP president Fred Royal, a member of the newly formed Freshwater for Life Action Coalition, who challenged Stepp and Milwaukee Mayor Tom Barrett to prioritize replacement of the state’s lead service lines. Barrett said there is limited federal or state funding available to help.
Royal noted that Milwaukee and the state figured out how to pay for a $500 million new basketball arena for the Milwaukee Bucks but seem baffled by how to replace lead pipes that may be contributing to the high rate of lead poisoning among the city’s children.
“We’re talking about whether it’s economically feasible to save our children in Milwaukee,” he said.
In the meantime, both Barrett and Edwards suggested residents install filters costing as little as $30 or use bottled water for drinking and cooking. Both agreed filters are effective, if maintained, but the long-term solution is to replace the pipes altogether.
In the wake of the Flint disaster, the state DNR issued grants totaling $14.5 million to 38 communities for full replacement of both the property owners’ portion and the city’s portion of lead service lines. Of that, $2.6 million was allocated to Milwaukee. Barrett chided Stepp for failing to give Milwaukee a larger portion of the funding given that the city has 40 percent of the estimated lead service lines in Wisconsin.
Stepp said her agency had to balance the needs of Milwaukee against those of other communities with lead service lines, including Ashland, Beloit, Kenosha, Janesville and Racine.
The panel did agree on this much: Replacing just the publicly owned portion of lead service lines will not solve the problem.
While such partial pipe replacement is required under some circumstances by the federal Lead and Copper Rule, that can actually make the situation worse. Researchers say lead can be released when those pipes are disturbed and when new copper piping reacts chemically with old lead lines. Leaving the property owners’ portion in the ground, Edwards said, “will poison children for generations.”
A test last year of six Milwaukee homes found levels of lead in the drinking water increased — in some cases astronomically — after the city did partial lead service line replacements during water main repairs. One home, for example, measured up to 328 parts per billion of lead after the replacement, compared to the baseline measurement of 6.5 ppb. While no amount of lead is considered safe, the U.S. Environmental Protection Agency has set 15 ppb as an action level, meaning steps should be taken to reduce lead in the water.
Barrett said the city has suspended all water main repair work in areas with lead service lines except in cases of emergency.
The testing also showed that even samples taken sequentially from the same tap can have radically different readings. At one home, lead concentrations in 12 samples ranged from 2 ppb to 199 ppb, according to the study.
Because of that extreme variability, Edwards said, testing for lead is almost useless. “No matter how much you sample, I will never ever say that water is safe,” he said.
Statewide, nearly 4,000 children, or 4.5 percent of those tested, were diagnosed as lead poisoned, according to 2014 state Department of Health Services figures, the most recent available. Among them were 2,244 children in Milwaukee. In that round of testing, 8.6 percent of Milwaukee children tested came up lead poisoned compared to 4.9 percent in Flint.
Lead’s effects are severe and permanent. Reduced intelligence, learning disabilities and developmental delays have all been attributed to lead exposure in young children, particularly those under age 6 whose developing brains are most vulnerable.
A 2013 study of Milwaukee fourth graders linked childhood lead poisoning to disruptive behavior at school. Researchers have found a greater likelihood of violent crime in adulthood among children in Cincinnati who were lead poisoned. Edwards also found an association between lead exposure in pregnant women in Washington, D.C. and an increased risk of fetal death.
The EPA has estimated that drinking water accounts for about 20 percent of average lead exposure, but as much as 85 percent of exposure for infants consuming formula made with tap water.
During a keynote speech, Edwards called the dangers posed by lead pipes a “government-made problem,” noting that cities including Milwaukee for many years required builders to use lead plumbing.
He also lambasted the “culture of corruption” at the EPA and the U.S. Centers for Disease Control and Prevention, which he said falsely assured residents in Flint and during a 2004 lead crisis in Washington, D.C. that their water was safe. He noted that eight people have been indicted so far in the Flint water disaster and predicted more criminal charges will be forthcoming.
Stepp, whose agency has been criticized for failing to crack down on polluters, said the problems in Flint convinced her Wisconsin must do more to protect residents from lead in their drinking water. She congratulated Edwards for his “courage” in bringing the Flint situation to light.
“If there’s any silver lining to Flint, Michigan, it’s this: it’s that people like you, everyday people, and policy makers at the state and federal levels are, for the very first time, talking about drinking water in a really serious way,” she said.
