After Wilsonville officials detected microcystins in a sample of water taken May 31, a follow-up test in Seattle showed no detectable level.
From the City of Wilsonville: Samples of local water delivered to a Seattle-area laboratory for testing on Friday, June 1, revealed no detectable level of microcystins in the local water supply, the cities of Wilsonville and Sherwood announced Monday.
A ‘non-detect’ result was returned this morning for three samples – source water, finished water and distributed water – supplied by the City of Wilsonville.
As an additional measure to ensure the health of the water supply, Wilsonville is sending samples to two laboratories to analyze seven straight days (June 1-7) of water.
