Washington Water Quality Facts
Before water reaches your tap, it is sourced from a complex system of surface water and groundwater from around Washington that includes lakes, rivers, streams, reservoirs, wells, and more. After water is pumped from these sources, it is purified, cleaned, and tested at a water treatment plant before being distributed throughout the state.
While the quality of Washington's water varies significantly depending on the region, residents of The Evergreen State often report their water being hard, which contributes to cloudy dishes and glassware, limescale or white scale buildup, and soap scum residue in bathroom areas.
Different parts of Washington can have very different water challenges as the quality of water across the state can greatly vary.
