"The city of Flint, which has been reeling for years over lead seepage from its pipes into its tap water, is accused of violating the terms of a major settlement agreement aimed at improving its water quality. Advocacy groups say the city is failing to disclose information about its efforts to replace its lead pipes.

They have filed a formal motion asking for a federal judge to force the Michigan city to comply with the agreement.

State and local authorities reached a settlement in March with advocacy groups to spend nearly $100 million to replace thousands of water lines within three years in Flint. It was approved by a federal judge and also requires that authorities make sure residents have filters installed and provide status reports about the program's progress."
