Groundwater contamination high near Wyoming coal ash ponds

August 13, 2019 GMT

CASPER, Wyo. (AP) — PacifiCorp is proposing corrective measures at two of its coal-fired power plants in southwest Wyoming after tests showed excessive groundwater contamination from coal ash ponds.

Tests that the company conducted found that groundwater on the Jim Bridger and Naughton power plants contained lithium and selenium at levels 100 times above what is considered safe.

PacifiCorp spokesman Dave Eskelson tells the Casper Star-Tribune that the groundwater contamination is confined to company property and is not a threat to the drinking water supply.


But environmental groups are wary of taking the company at its word, pointing to the irreversible harm groundwater contamination causes to the environment and the public.

PacifiCorp is accepting public comment on contamination issues at its coal ash ponds until Aug. 26.
