Does Santa Cruz County Fairgrounds have drinking water violations?

EPA's records list 10 violations for this system; 2 are health-based, and the most recent began in October 2024. The violations listed here began between October 1982 and October 2024. By type: 4 public notice, recordkeeping or other, 3 monitoring and reporting, 2 required treatment not met and 1 reporting. The contaminant or rule involved most often is Lead and Copper Rule (4 of them). EPA lists 4 as resolved, 4 as archived and 2 as addressed. 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement.
