I just got an email from the ACLU with this link:
A coalition of local citizens and national groups filed suit today to ask a federal court to step in and secure access to safe drinking water for the people of Flint, Michigan.
Alleging violations of the federal Safe Drinking Water Act, the complaint was filed in the U.S. District Court for the Eastern District of Michigan by the ACLU of Michigan, the Natural Resources Defense Council, Concerned Pastors for Social Action and Flint resident Melissa Mays.
“Flint is Exhibit A for what happens when a state suspends democracy and installs unaccountable bean counters to run a city,” said Michael J. Steinberg, legal director of the ACLU of Michigan.
[...]
The lawsuit asks a federal court to compel the city and state officials to follow federal requirements for testing and treating water to control for lead and to order the prompt replacement of all lead water pipes at no cost to Flint residents. The groups and Ms. Mays also seek appropriate relief to remedy the health and medical harms to Flint residents from the lead contamination. The lawsuit is not seeking monetary damages.
On that page there are also links to PDFs of the complaint and the Notice of Intent to Sue.
