DETROIT (AP) — A judge granted preliminary approval Thursday to a $641 million deal that would benefit Flint residents who were harmed by lead-contaminated water.

The settlement includes $600 million from the state of Michigan, although Flint, an area hospital and an engineering firm are also part of the agreement. U.S. District Judge Judith Levy signed off in a 72-page opinion.

“There may be no amount of money that would fully recognize the harm the residents of Flint have experienced, including their anxiety, fear, distrust and anger over the events of the last seven years,” Levy said. “Litigation has its benefits but also its limitations, and the preliminary approval of this settlement does not affect or preclude other avenues of redress.”

Preliminary approval triggers a monthslong process during which Flint residents can object and pursue their own claims, Levy said.

Regulators in then-Gov. Rick Snyder’s administration allowed Flint to use the Flint River in 2014-15 without treating the water to reduce corrosion. As a result, lead in old pipes broke off and flowed through taps.

Separately, experts have blamed the Flint River water for an outbreak of Legionnaires’ disease, which led to at least 12 deaths in the Flint area.

Snyder last week was charged with two misdemeanor counts of willful neglect of duty in Flint. Eight other people were also charged, including two health department officials who are blamed for the deaths of nine people with Legionnaires’.
