How does Toledo MHP 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. Groundwater means the system draws its water from wells or springs fed by underground aquifers. 6,179 California systems (83%) list groundwater as their primary source.
Who owns and regulates Toledo MHP?
EPA lists Toledo MHP 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 Toledo MHP have drinking water violations?
Of the 12 most recent violations in EPA's records, 5 are health-based, and the most recent began in March 2026. The violations listed here began between August 2025 and March 2026. By type: 6 monitoring, 5 required treatment not met and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Revised Total Coliform Rule (6 of them). EPA lists 5 as archived, 4 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.
