Coal-fired power plants used to dispose of coal ash by dumping it into ponds, resulting in millions of cubic yards of toxic waste in pits in the ground.
Eli Chen, St. Louis Public Radio’s science reporter, published a two-part investigation into coal ash ponds in Missouri. Read her coverage: Data From Missouri Utilities Shows Polluted Groundwater Near Massive Pits Of Coal Waste
Environmental activists have long expressed concerns that coal ash — which contains mercury, lead, arsenic and other cancer-causing chemicals — could contaminate groundwater and pose health risks to rural residents who depend on wells for their drinking water. There is also fear that future floods could cause the nearby Missouri and Mississippi rivers to spill into the ponds and local waterways. Last fall, floodwaters caused by Hurricane Florence breached a coal ash pond in Wilmington, North Carolina.
