Toxins found near almost all coal ash ponds tracked by industry

Environmental watchdogs say the power industry’s own data show widespread groundwater contamination near sites storing coal ash, a toxic byproduct of burning coal to generate electricity.

Groundwater monitoring wells near coal ash storage sites used by 265 coal power plants reveal unsafe levels of arsenic, lithium and other pollutants in most of them, according to an assessment by the Environmental Integrity Project, Earthjustice and other environmental groups being released Monday.
