Giant smoke stacks and industrial dump sites are no longer the only water quality problem on the Columbia River. a recent study has found that our day to day life has a major impact as well.
U.S. Geological Survey researchers looked at nine cities along the river, from Wenatchee to Longview, Wash. They detected hundreds of contaminants flowing from wastewater treatment plants and stormwater runoff.
Hydrologist Jennifer Morace says the toxic contaminants included things like shampoo and pharmaceuticals.
