Galt Water Hardness & Quality Report (2026)

The City of Galt Water Company, operated by the Public Works Utilities Division, serves approximately 23,230 residents in Galt, California, within Sacramento County. Water is sourced exclusively from six active groundwater wells in the local aquifer system, with no surface water intakes or treatment plants beyond wellhead disinfection. Distribution occurs via pipelines from the utility headquarters at 380 Civic Dr. Contact Utility Manager Richard E. Bisnett at (209) 366-7260 for records or the annual drinking water quality report.

The supply originates in the Cosumnes River Groundwater Basin, a key aquifer in the Sacramento Valley. Water infiltrates through Quaternary alluvial sediments — sands, gravels, and clays derived from Sierra Nevada weathering and river deposition. These formations contain limestone fragments and dolomite that release dissolved minerals as water percolates through, contributing calcium and magnesium to the supply. Despite the presence of carbonate-bearing sediments, the measured hardness registers soft at 36.9 mg/L, reflecting the basin's overall mineral balance and aquifer chemistry.

At 36.9 mg/L, Galt's water is classified as soft, meaning scale buildup in pipes, appliances, and fixtures is minimal. Soap lathers readily and rinses cleanly, and a water softener is not required for most households. The 2024 Consumer Confidence Report confirms compliance with state and federal standards, noting low-level naturally occurring arsenic. pH measures around 9–9.6, which is alkaline; fluoride is natural at 0.3 ppm with none added; sodium is at 55 ppm. No PFAS or lead/copper violations are reported; treatment is basic disinfection at wells, with current reports available via cityofgalt.org.
