E.coli monitoring on the Columbia River



Riverkeeper’s Swim Guide app uses real time E.coli data collected by Columbia Riverkeeper volunteers to flag Columbia River beaches that are safe or unsafe for swimming, or have no data.  While Swim Guide does not consider toxic pollution or other potential environmental concerns, it is a useful tool for people who want to avoid bacterial contamination.








 Riverkeeper’s water quality data also may be viewed on the statewide databases of both Oregon DEQ and Washington Dept. of Ecology. Our data is available to the public and we encourage its widespread use. We ask that you let us know if you use our data for research, policy, or educational purposes.
