Who owns and regulates Deer Meadows?

Does Deer Meadows have drinking water violations?

EPA's records list 10 violations for this system; none is health-based, and the most recent began in January 2026. The violations listed here began between July 1998 and January 2026.

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.
