About Keizer's Water Supply
Water Utility: City of Salem Water
Water Source: Willamette River (Groundwater)
Population Served: 38,585
Hardness: 15 PPM (0.9 grains per gallon)
Keizer draws its drinking water from groundwater sources — Willamette River. Groundwater typically requires less treatment than surface water because the earth acts as a natural filter. The tradeoff: dissolved minerals from underground rock formations, which is why mineral content varies by aquifer depth and geology. The geological profile determines hardness, iron, and trace mineral levels. The system serves 39,000 residents.
Water quality can vary by neighborhood and season. For your exact numbers, request City of Salem Water's Consumer Confidence Report (CCR) or test your own tap.
