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, Golden State Water’s top priority is protecting the quality of your water supply.
To ensure the quality of your drinking water, Golden State Water’s team regularly monitors and tests for more than 230 regulated and unregulated contaminants in each of our 37 water systems. If any contaminants are found, they are listed in the Water Quality Report that is submitted annually to customers. However, most of the contaminants we test for are not found, so they are not listed in the water quality report.
Water quality test results are directly submitted by the 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.
