High uranium levels found near Denver water supply
April 16, 2010
DENVER (AP) – Groundwater near a creek that flows into Denver’s water supply contains uranium levels that are 1,000 times higher than the human health standards.
State health officials say contamination at Cotter Corp.’s closed Schwartzwalder Mine is approaching emergency conditions and has given the company until Monday to submit a plan to deal with it.
The mine in Jefferson County is near Ralston Creek, which flows into Denver Water’s Ralston Reservoir. The reservoir supplies water to Denver and Arvada.
Cotter vice president John Hamrick says they’re considering several methods to deal with the contamination, including creating a wetland.
