Riverkeeper Epstein

Columbia Riverkeeper Director Lorri Epstein, at left,  closely examines a sample of river water at the Hood River Spit. The lab needs 100 mg of water for the best possible sample. 

There’s nothing more refreshing on a hot summer day than to splash in the cool Columbia River or the falls and streams that feed into it.

But before you dive, take a minute to research your favorite swimming hole. If you like to dive with a mouth-wide-open smile on your face, you could emerge from the water with more than a cool attitude.

Riverkeeper sign

Signs like the one above can be seen at recreation sites throughout the Gorge where samples have returned elevated levels of contamination.
