Northshore’s drinking water (purchased from Seattle Public Utilities) consistently meets or exceeds strict regulations set by the Environmental Protection Agency (EPA) and the Washington State Department of Health (DOH).  These regulations limit contaminants in water provided by public water systems.

The annual Drinking Water Quality Report shows exactly how your tap water tested for specific compounds.  It also outlines the daily steps we take to make sure it stays safe and clean. 

The annual publication reports on data gathered from the previous year.  For the most current water quality data, SPU publishes quarterly water analyses.

If you have questions about water quality, please call or email our Water Quality Office at (425) 398-4419, waterquality@nud.net.
