A study by the Environmental Integrity Project, with assistance from Earthjustice, found that more than 90 percent of U.S. coal-fired power plants with monitoring data are contaminating groundwater with unsafe levels of toxic pollutants.
Groundwater near 242 of the 265 power plants with monitoring data showed unsafe levels of pollutants from coal ash such as arsenic or lithium.
The data for the study came from the industry itself and Abel Russ, lead author of the report, argues there needs to be more federal regulation on coal ash.
The authors of the report warn against the roll back of regulations by the EPA and argue this is an issue of human health and environmental protection.
