Purchased surface water means the system buys surface water from another public water system rather than drawing its own. 506 California systems (6.8%) list purchased surface water as their primary source.
Who owns and regulates Uc Desert Research and Extension Center?

The CA state drinking water program is its primacy agency, the regulator with primary enforcement responsibility for the system under the Safe Drinking Water Act. 7 of the 76 active systems in Imperial County (9.2%) are also owned by a state government.
Does Uc Desert Research and Extension Center have drinking water violations?
Of the 12 most recent violations in EPA's records, 9 are health-based, and the most recent began in October 2024. The violations listed here began between July 2013 and October 2024. By type: 8 contaminant level above the legal limit, 2 monitoring and reporting, 1 reporting and 1 required treatment not met. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (9 of them). EPA lists 8 as resolved, 2 as addressed and 2 as archived. 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement. 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.
