Annual Water Quality Reports Now Available for California Water Service Customers

SAN JOSE, Calif.—California Water Service (Cal Water) has published its annual Consumer Confidence Reports (CCR) for each of its water systems and invites customers to learn about the quality of their local water supply. Customers can access their 2024 CCRs, also called water quality reports, along with previous years' reports online at calwater.com/ccr.

Importantly, the reports confirm that Cal Water met all primary and secondary, federal and state water quality standards set for drinking water in 2024. The reports also provide comprehensive information on the local water supply, standards, testing, current hot topics, and more for last year. Customers who do not have internet access may obtain a copy by contacting their local Cal Water office.

"Providing safe, clean, reliable drinking water to our customers' homes is our top priority," said Sophie James, Vice President of Water Quality and Environmental Affairs. "We treat the water to make it safe to use and drink, test it to confirm it meets regulatory standards, and stay on top of emerging water quality regulations, focusing on our customers' water, so they don't have to."

Cal Water focuses relentlessly on water quality by doing the following:

• Conducting more than 600,000 water quality tests per year for more than 300 contaminants in its state-certified, state-of-the-art lab.
• Investing in technologies and infrastructure to remove chemicals, contaminants, and other pollutants from the raw water supply.
• Maintaining and upgrading the water system infrastructure needed to transport water from its source through pumps, tanks, and pipes to customers' homes.
