August 2026 · Orevant Compliance Intelligence
California has more than 7,000 public water systems regulated by the State Water Resources Control Board (SWRCB) Division of Drinking Water alongside federal EPA requirements. Compliance in 2026 is more demanding than ever — PFAS MCLs are now in effect, LCRR requires active service line inventories, and annual Consumer Confidence Report filings have no deadline flexibility.
The EPA sets limits of 4 ppt for PFOA and PFOS. California community water systems must complete initial monitoring within 3 years of the rule. A violation triggers public notification and corrective action. California DDW may impose additional requirements beyond the federal baseline.
California systems must complete a full lead service line inventory and submit it to the State DDW. The inventory classifies every service line as lead, galvanized requiring replacement, non-lead, or unknown. California AB 2060 aligns with and in some cases exceeds federal LCRR requirements.
Community water systems must deliver a CCR to every customer by July 1 each year. Missing the deadline is a direct compliance violation. The report must include all detected contaminants, source water information, and educational language on lead.
