The Environmental Protection Agency is launching a civil rights investigation into whether the state of Mississippi discriminated against the majority-Black residents of Jackson when it refused to use federal funds to address the city’s dangerous water crisis. The EPA said Thursday it’s probing Mississippi’s Department of Health and Department of Environmental Quality over its role in the crisis that left tens of thousands of mostly Black households without drinking water. The main water treatment plant in Jackson was damaged after torrential rains and flooding in late August. Some viral videos showed undrinkable brown liquid coming out of taps.
