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 North Muroc Mutual Water Company?

EPA lists North Muroc Mutual Water Company as privately owned.

Does North Muroc Mutual Water Company have drinking water violations?

Of the 12 most recent violations in EPA's records, 8 are health-based, and the most recent began in January 2021. The violations listed here began between January 2010 and January 2021. By type: 8 contaminant level above the legal limit, 3 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Arsenic (8 of them). EPA lists 10 as resolved 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. 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.
