Water Quality Notice

Northshore Utility District water customers are asked to look for a notification from Seattle Public Utilities (SPU) regarding water testing results from December 29, 2015.  The notification will come in the mail beginning January 15, 2016.

The notice describes that operator error caused high turbidity water to reach the Tolt Water Treatment Facility filters.  Turbidity is a measure of how cloudy the water appears.  The incident did not cause a safety or health concern and had no impact on the taste of drinking water.  However, because the treatment standard was not met on this particular day, the Washington State Department of Health requires that water customers be notified.

Northshore Utility District purchases its drinking water from SPU and delivers it through the District’s distribution system.  NUD water customers can contact the District’s Water Quality Officer at (425) 398-4419 with specific questions.
