An updated interactive map by The Environmental Working Group shows where drinking water for more than 19 million Americans are contaminated by the cancer-causing solvent trichloroethylene (TCE). The map update adds 243 new detections of toxic TCE drinking water to the earlier version of the map released in 2018. The map now identifies 426 areas affecting U.S. drinking water.
Drinking water contaminated by TCE has been linked to leukemia and liver and kidney damage. It has been used for degreasing and cleaning metal parts in factories but was classified as a “human carcinogen” in 2011 by the EPA.
