In Flint, Michigan, the ACLU has filed a class action lawsuit arguing the public school system has not done enough to provide children exposed to lead with sufficient educational services. Flint’s lead poisoning began when an unelected emergency manager appointed by Michigan Governor Rick Snyder switched the source of the city’s drinking water to the corrosive Flint River in 2014. Lead is a known neurotoxin, which can cause significant developmental delays, especially in children. The lawsuit, filed in the U.S. District Court in the Eastern District of Michigan, argues the school system is not adequately screening lead-exposed children for disabilities and providing educational interventions, and that the Michigan Department of Education has not sufficiently funded the Flint school district.
