A new study by three top environmental groups reveals another 39 coal ash threats in 21 states, bringing the total number of known coal ash threats to 137 in 34 states.
The report by the Environmental Integrity Project, Earthjustice, and the Sierra Club details the newly identified slurry ponds and impoundments filled with toxic coal ash that threaten drinking water supplies and public health at sites around the country.
Earlier this year the groups identified 31 coal ash disposal sites in 14 states, adding to the 67 sites already identified by the Environmental Protection Agency. The latest report brings the total number to 137 sites where coal ash threatens public health and water supplies.
The U.S. EPA is currently grappling with how to regulate the toxic coal ash threat, which is now checked only by individual state laws that have failed to adequately protect the public from this growing problem.
