LANSING (WWJ/AP) – Environmental and civil rights groups are asking a federal judge to order the prompt replacement of all lead pipes in Flint’s water system to ensure residents of the Michigan city — and beyond — have a safe drinking supply.

A lawsuit filed Wednesday morning seeks an order forcing city and state officials to remedy alleged violations of the federal Safe Drinking Water Act, including a failure to properly treat the water for corrosion, test it for lead, notify residents of results and accurately report if the correct sample sites are being selected. Flint residents are currently unable to drink unfiltered tap water due to the contamination, and tests have shown high lead levels in some children’s blood.

“The only way to permanently and completely fix the problem of lead in drinking water is to conduct the full replacement of the lead-containing pipes and solder in a water system,” said Sarah Tallman, a lawyer with the National Resources Defense Council. The group filed the complaint on behalf of citizens along with the American Civil Liberties Union of Michigan, the Concerned Pastors for Social Action and Melissa Mays, a Flint resident.

Mays told WWJ’s Charlie Langton they gave officials a 60-day notice of their intent to sue back in November.

“We are forced to sue the state because they never changed their testing and monitoring protocol and they are fighting us on doing the right thing in being compliant with the EPA’s lead and copper rules,” she said. “We gave them notice under the Safe Drinking Water Act back in November and it’s up. So, today we’ve filed and we’ve got to sue, and it’s unfortunate.”

Gov. Rick Snyder’s administration has estimated it could cost up to $55 million to repair what officials have estimated are 15,000 damaged lead service lines leading from water mains to homes and other buildings. The complaint says the pipes should be replaced at no cost to customers.

While Flint is the focus of the lawsuit, Mays said it’s really about all citizens who live in Michigan.

“All the ways that they’ve failed us here in Flint, they are failing other cities. We’re finding that there are loopholes in the testing protocol for other cities and there’s high lead, if you do the true testing, in other cities in Michigan and that means that they are failing us still,” she said. “This lawsuit is demanding federal court oversight in the way the MDEQ operates with the water. We’ve got to do something to change the laws so that this just doesn’t happen again.”

The suit names as defendants the city of Flint, state Treasurer Nick Khouri — who continues to have budget powers as the city transitions away from state management — state-appointed officials on the Flint’s Receivership Transition Advisory Board and city administrator Natasha Henderson, who was hired by one of Flint’s former emergency managers.

“The people of Flint cannot rely solely on the government entities that have created this problem to fix it,” Tallman said. “We are seeking federal court intervention because the government at every level has evaded responsibility for addressing this crisis.”

It remains unclear how badly the pipes were damaged after the decision in 2014 to use the Flint River as the city’s drinking water source without adding a chemical to control corrosion. That caused lead to leech into the water for a year and a half and contributed to the spike in child lead exposure before state and officials fully acknowledged the problem in early October.

Flint has reconnected to Detroit’s water system while awaiting the completion of a new pipeline from Lake Huron. But Mays said many residents, herself included, still have brown water coming out of their taps.

“We’re still not brushing our teeth, we’re still not drinking it or cooking with it. A lot of people still have discolored water with stuff floating in it, and so we want the pipes fixed so we don’t have to live off of bottled water and beg for bottled water for the next 10 years,” Mays said. “We’re tired of bottled water, which of course we appreciate the donations from people around the world at this point, but it’s still not safe. All the contaminates are in there, everybody knows it.”

The lawsuit expresses doubt about whether the city can maintain optimal corrosion treatment when it switches to the new water source later this year.

Much of the blame for the emergency has been put on the state Department of Environmental Quality because staff told Flint water officials not to treat it for corrosion until after two six-month monitoring periods. But the suit also focuses on problems with the city’s monitoring of lead. It alleges the city is not providing comprehensive, reliable information to identify locations with lead lines and is under-testing homes with a higher risk of lead exposure.

The plaintiffs hope “independent experts would come in to assist and advise and oversee the water’s system implementation,” Tallman said.

The U.S. Environmental Protection Agency last week issued an emergency order directing the state to take actions to protect public health and said it would begin sampling and analyzing lead levels. Michigan’s interim top environmental regulator said his agency would comply but contended that many of the actions have already been undertaken and questioned the order’s legality.

Snyder said in recent days that his administration has requested assistance from EPA experts. A task force he created also has recommended that an unbiased third party declare when the water is safe to drink again without a filter.

At least three other suits have been filed since the crisis was exposed in the fall. Two seek class-action status and financial compensation; another asks a judge to declare that users do not have to pay their water bills.
