Does Sandy Point Improvement Co 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 January 2005 and July 2012. By type: 10 monitoring and reporting and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Arsenic (4 of them). EPA lists 6 as resolved and 6 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.
