In the lawsuit, the families allege that their children are the victims of developmental disabilities that stem from the high levels of lead they ingested when Michigan switched Flint's water source from Detroit's system to the Flint River to cut costs. Without corresponding treatment for lead levels, the water flowing from Flint residents' taps smelled and tasted strange, though it took over a year for testing to reveal high levels of lead and for Flint citizens' water to be switched back.
The group's lawsuit cites the Safe Drinking Water Act, a federal law that establishes guidelines for safe public drinking water throughout the country, set by the U.S. Environmental Protection Agency. It's not the first lawsuit filed, but it is the most recent.

Earlier this year, President Barack Obama approved federal funding for the majority black city of nearly 100,000.
