GALT, CA (MPG) - The City of Galt has released its 2025 Consumer Confidence Report, reaffirming that the city's drinking water met all state and federal drinking water standards throughout the year while outlining ongoing infrastructure improvements and conservation efforts.

Prepared in May, the report covers water quality data collected during the 2025 calendar year and provides residents with information about the city’s water supply, treatment process and testing results.

The city supplies drinking water through four active wells and one standby well that draw from the Cosumnes Subbasin. The groundwater is treated to remove naturally occurring iron, manganese and arsenic, while low levels of chlorine are added to disinfect the water before it enters the city’s closed-loop distribution system.

In 2025, Galt’s wells pumped more than 1.4 billion gallons of water.

According to the report, the city conducts extensive water quality testing to comply with standards established by the State Water Resources Control Board and the U.S. Environmental Protection Agency. While Galt’s drinking water meets all regulatory standards, it contains low levels of naturally occurring arsenic that remain below the Maximum Contaminant Level. The report also stated that the Environmental Protection Agency continues to study the long-term health effects of low-level arsenic exposure.

The report includes a reminder to residents that lead in drinking water typically comes from household plumbing rather than the city’s water system. Residents are encouraged to flush taps for 30 seconds to two minutes before using water for drinking or cooking if it has been sitting in pipes for several hours.

In addition to water quality results, the report highlights several infrastructure projects aimed at meeting future demand.

Construction began in fall 2025 on the Carillion Deep Well Expansion and Storage Reservoir Project, which includes a new 1.5-million-gallon storage tank, a replacement deep well and expanded treatment capacity. Once complete, the project is expected to increase water production by 2,000 gallons per minute and eliminate the need for arsenic treatment at that facility. Construction is expected to wrap up in fall 2027.

The city also began converting a test well at the Industrial Water Treatment Plant into a production well in September 2025. The project is expected to increase water production by an additional 1,000 gallons per minute when completed in fall 2026.

The report notes that Galt continues working with six regional agencies through the Cosumnes Groundwater Authority to ensure the long-term sustainability of the Cosumnes Subbasin. Since implementing water conservation measures more than a decade ago, the city has reduced groundwater pumping by about 25% and now accounts for roughly 4% of the water withdrawn from the subbasin.

The report also states that testing found no detectable levels of per- and polyfluoroalkyl substances, commonly known as PFAS, in the city’s drinking water. The city continues monitoring for the chemicals as required by the State Water Resources Control Board.

Although statewide drought restrictions are no longer in place, the city continues encouraging residents to conserve water through practices such as repairing leaks promptly, watering landscapes efficiently and installing water-saving fixtures.

Residents with questions about the city’s drinking water can contact the Public Works Utilities Division at 209-366-7260. The full Consumer Confidence Report is available on the City of Galt’s website at cityofgalt.org.
