How does Havasu Water Company compare with other water systems in California?

What does “community water system” mean?
A community water system serves at least 15 connections used by year-round residents, or regularly serves at least 25 year-round residents. Homes, apartments and mobile-home parks are served by these. California has 2,997 active community water systems, 40% of the state's 7,479 active systems. Surface water means the system draws its water from rivers, lakes, streams or reservoirs. 609 California systems (8.1%) list surface water as their primary source.
Who owns and regulates Havasu Water Company?
EPA lists Havasu Water Company as privately owned. The EPA Region 09 is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act.
Does Havasu Water Company have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in February 2026. The violations listed here began between April 2025 and February 2026. By type: 4 monitoring and reporting, 4 contaminant level above the legal limit, 3 public notice, recordkeeping or other and 1 required treatment not met. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (5 of them). EPA lists 6 as archived, 3 as resolved and 3 as unaddressed. Archived means the violation was not marked resolved but is more than five years past the end of the noncompliance period, so it no longer counts toward current compliance status. Resolved means at least one resolving action is on record: the system returned to compliance, the rule no longer applies, or no further action was needed. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement.
