“As evidenced by the roughly 300 boil water notices that have been issued over the past two years, the multiple line breaks during the same timeframe, and the recent drinking water crisis, it’s clear this community has suffered long enough,” Regan said.

Kim’s letter, which was obtained by local NBC and ABC News affiliates, highlights alleged violations of the Safe Drinking Water Act the Justice Dept. believes have occurred as a result of state and local officials failing to protect public health. They include inadequately staffing water treatment plants, a lack of an alternative water supply plan and a failure to meet deadlines under a prior EPA compliance order. Also, Kim wrote that they failed to install corrosion controls, and tests showed exceedances of both haloacetic acids (HAA5) and turbidity limits.

Federal officials want a comprehensive plan that could include temporary third-party management of Jackson’s water system, Kim wrote.

“I’m happy that we’re moving forward in a collaborative way,” Lumumba said.

Jackson is also facing a federal lawsuit filed Sept. 16 by four residents who accuse current and former officials of neglecting the city’s water supply for decades. The suit alleges residents were deprived of their right to bodily integrity under the 14th Amendment. It also accuses two firms that provided water services to Jackson, Siemens Industry Inc. and Trilogy Engineering Services LLC, of professional and simple negligence.

Emergency Repairs

Outside experts have joined the efforts to make emergency repairs at the Curtis water treatment plant. The plant has both conventional and membrane treatment systems, and the team repaired equipment on both sides. Raw water pumps were removed by crane for repairs and then reinstalled. Membrane trains and conventional sedimentation basins were cleaned. Members of the multistate team also worked on Jackson’s smaller-capacity J.H. Fewell Water Plant.
