EAST WENATCHEE, Wash. (AP) -- The state Department of Ecology is tracking two sewage spills into the Columbia River.
The agency is working with East Wenatchee officials to determine the cause of a 500,000-gallon sewage spill into the river overnight Sunday. An operator at the city's wastewater treatment plant discovered the spill Monday.
The plant has since returned to normal operations.
Meanwhile, officials in Trail, British Columbia are working to repair a broken sewer line that is spilling raw sewage into the river about 10 miles north of the U.S.-Canada border. Canadian officials estimate that up to 15 million gallons will ultimately be spilled by the time repairs are made Tuesday.
The Northeast Tri-County Health District in Colville is warning citizens to stay away from the river until the sewage has finished running downriver.
