Its population served is well below the county average of 474 people per system, and accounts for 0.2% of the 51,627 people reported by systems filed under the county.

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 Riverside Crossing MHP?

Does Riverside Crossing MHP have drinking water violations?

Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in October 2024. The violations listed here began between February 1984 and October 2024. By type: 8 public notice, recordkeeping or other, 2 monitoring and reporting, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Lead and Copper Rule Revisions (2 of them). EPA lists 8 as archived, 2 as unaddressed and 2 as resolved. 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. Unaddressed means the violation is not resolved or archived and is not yet covered by formal enforcement. 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.
