Artondale Water Hardness & Quality Report (2026)

Washington Water Service draws all its drinking water from a network of groundwater wells serving the Artondale and Bayview areas of Pierce County, near Gig Harbor, Washington. Unlike many utilities, Artondale relies solely on these underground sources, with no surface water from reservoirs or rivers involved. While there aren't specific named treatment plants, the wells are continuously monitored, and any showing quality issues are temporarily taken offline. The watershed for this groundwater supply is the local recharge area on the Kitsap Peninsula, which receives water as precipitation filters through glacial and alluvial deposits within the Puget Sound basin.

The geology beneath Artondale is characterized by the Pleistocene Vashon Drift, a substantial layer of glacial till, sand, and gravel. This sits atop the Tertiary Puget Group, composed of sandstones and siltstones from the Oligocene-Miocene periods. This dual aquifer system produces water with a moderate mineral content. This is due to ion exchange with carbonate-rich glacial sediments and the water's extended time spent leaching minerals from the sedimentary bedrock, giving it a higher mineral count than the softer, rainwater-fed supplies found elsewhere in this part of Washington.

Homeowners in Artondale might notice a moderate amount of scale building up in appliances like water heaters and dishwashers. This buildup can reduce efficiency and increase energy costs over time. You may also find faucet aerators and showerheads clogging more noticeably after a year or two, requiring periodic cleaning. To combat these effects and extend appliance life, a water softener is often recommended. This will also improve how efficiently soap and detergents lather. While the water meets all EPA drinking water standards and has shown no recent detections of PFOS from the wells that were temporarily offline, customers can find more details on water quality and PFAS status on the Washington Water Service website.
