At 91 percent of coal fired power plants with monitoring data, disposal sites are contaminating groundwater with unsafe levels of toxic coal ash, according to a national report from Earthjustice and the Environmental Integrity Project. Starting in March 2018, federal coal ash regulations require that coal-fired electric facilities publish their groundwater monitoring data, which became the basis for the report. Earthjustice, a MacArthur grantee, includes an interactive map that visualizes the geographic extent of contamination at sites including 265 coal plants with over 550 coal ash ponds and landfills.
