Lead Drinking Water Standards
Recent media reports in some parts of the country have highlighted concerns related to elevated levels of lead in the drinking water.
Golden State Water would like to assure customers that we monitor and test regularly to ensure the water we deliver to customers meets all state and federal drinking water standards, including those for lead and copper as found in the Revised Lead and Copper Rule.
Flushing
Everybody knows that hydrants are essential to provide water for fire protection, but they also serve a critical role in ensuring customers receive reliable, quality water service at their home or business.
Hydrants are necessary to flush the underground water system, improving water quality by removing mineral and sediment deposits that accumulate over time. While not harmful to customers, the substances can cause aesthetic water quality issues when they are not periodically flushed from the system.
Types of Contaminants
Golden State Water’s team regularly monitors and tests for more than 230 regulated and unregulated contaminants in each of our 39 water systems.
Cross-Connection Control Protection Program
Golden State Water Company (GSWC) is committed to providing our customers with water that meets all state and federal drinking water standards. This precious resource, once it enters businesses and homes, gets used in many ways; some of which may pose a potential contamination risk to the water supply. Ensuring that the integrity of our community water supply is maintained in the systems is therefore a responsibility that GSWC must also extend to you, our customer.
