YAKIMA, Wash. – A case involving cross border pollution of the Columbia River rests in the hands of a federal judge today. A Native American tribe and the state of Washington have sued to hold a Canadian mining giant responsible for smelter waste that washed downriver from British Columbia into Washington.

The smoky skies over Seattle are likely from Asia and not Western fires, says Cliff Mass, KPLU weather forecaster and University of Washington professor.

RICHLAND, Wash. – 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.

But that’s one way environmentalists and scientists sometimes describe it, because the shape of Puget Sound is an important factor when it comes to keeping it clean.

The sweet smell from your dryer vent could contain toxic pollution.

A new study from the University of Washington found hazardous chemicals in the air after clothes were laundered with scented detergents and dryer sheets. At least two of the chemicals are considered carcinogens by the Environmental Protection Agency.
