A new report written by Environmental Integrity Project, Earthjustice, Prairie Rivers Network and Sierra Club, revealed widespread pollution of the groundwater surrounding 90 percent of reporting Illinois coal ash dumpsites.
The report is based on industry data made publicly available for the first time this year because of a requirement in federal coal ash regulations. It concludes that 22 of Illinois 24 coal ash dumpsites with available data have released toxic pollutants including arsenic, cobalt, and lithium, into groundwater.
