Does Hartly Mobile Home Park have drinking water violations?

Of the 12 most recent violations in EPA's records, 4 are health-based, and the most recent began in July 2015. The violations listed here began between July 1995 and July 2015. By type: 8 public notice, recordkeeping or other and 4 contaminant level above the legal limit. The contaminant or rule involved most often is Consumer Confidence Rule (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.
