Does Stonetown Oaks MHP LLC have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in July 2012. The violations listed here began between March 1999 and July 2012. By type: 9 monitoring and reporting and 3 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 8 as resolved and 4 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.
