Commitment to Water Quality

Golden State Water Company is committed to providing our customers with water that meets all state and federal drinking water standards. With more than 500 highly qualified employees, our expert team at Golden State Water includes scientists and engineers whose top priority is protecting the quality of your water supply.

To ensure the quality of your drinking water, Golden State Water regularly monitors and tests for more than 230 regulated and unregulated contaminants in each of our 39 water systems and is continuously tracking state and federal regulations as they evolve. If contaminants are detected through testing, they are listed in a Consumer Confidence Report (CCR) that is shared annually with customers. It is important to know that most of the contaminants we test for are not found, and therefore not listed in the CCRs.

Water quality test results are directly submitted by a State certified laboratory to the State of California’s Division of Drinking Water (DDW) and recorded on the State’s website for full transparency. Click here to view test results on the DDW website.

If you have questions regarding drinking water regulations or information about your local drinking water, please feel free to contact our 24/7 customer service center at 800.999.4033 and ask to speak with your local Water Quality Engineer.

Flushing

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.

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.
