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 38 water systems.
Cross-Connection Control Protection Program
Golden State Water Company’s Cross-Connection Control Program is designed to protect the potable water supply (water that is safe for drinking) from any unwanted flow from residential, commercial, industrial or institutional water sources. A cross-connection is a connection or potential connection between a potable water system and any source containing water or other substances that are not safe for human consumption.
