A minimum of 4 microbiological water samples are taken at various sites in the District Water system each month. We also test the water for chemical makeup and possible contaminants levels at Alexin Analytical of Oregon, a state Certified Water Testing Laboratory. If you wish additional information about our water testing and results, our lab telephone number is (503) 639-9311.

Periodically, water samples are sampled from residences within the District and analyzed for lead and copper levels. These water tests are done according to the required guidelines of the Drinking Water Program of the Oregon Health Authority.
