Report shows toxic contamination at coal ash sites throughout Illinois

A new report published by several state environmental groups shows severe pollution of groundwater at nearly every known coal ash storage site in Illinois.

The report states that groundwater tests show unsafe levels of toxic chemicals and heavy metals at 22 of 24 Illinois coal-fired power plants. The tests were done by the companies that own the sites, collated by the environmental groups, and released this week.
