Water Quality Testing Labs


While Cal Water conducts rigorous testing at the source and within our distribution system, we recognize the value of home water testing for customer peace of mind. Accredited labs can provide additional testing services, addressing concerns related to home plumbing or health issues. It's important to verify a lab's accreditation status and certification for specific analyses before proceeding with testing to ensure accurate results.
