Does San Isidro MHP have drinking water violations?
EPA's records list 11 violations for this system; 3 are health-based, and the most recent began in December 2022. The violations listed here began between August 1991 and December 2022.

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.
