Federal study finds high uranium concentration in some wells
SPOKANE, Wash. (AP) — The federal government says some water wells in northeastern Washington have high uranium concentrations, sometimes as much as 40 times the level considered safe for drinking water.
That’s according to a new study from the U.S. Geological Survey, which sampled water from 13 wells and looked at historical data on uranium concentrations.
The Spokesman-Review reports that half the wells sampled had levels of uranium above 30 micrograms per liter, the Environmental Protection Agency’s standard for drinking water.
The study found 60 percent of wells in the historical data had uranium concentrations above safe drinking water guidelines.
The study looked at portions of Ferry, Stevens and Pend Oreille counties, most of Spokane County, and parts of Okanogan, Douglas, Grant, and Lincoln counties. About 125,000 there get their water from private wells.
