Does Buckingham Park Water District have drinking water violations?
Of the 12 most recent violations in EPA's records, 8 are health-based, and the most recent began in January 2015. The violations listed here began between April 1989 and January 2015. By type: 5 contaminant level above the legal limit, 3 required treatment not met, 3 public notice, recordkeeping or other and 1 monitoring and reporting. The contaminant or rule involved most often is Haloacetic acids (HAA5) (3 of them). EPA lists 9 as resolved and 3 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.
