Does Hallsdale-Powell U.D. have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in April 2016. The violations listed here began between January 2011 and April 2016. By type: 11 monitoring and reporting and 1 contaminant level above the legal limit. The contaminants or rules involved are Haloacetic acids (HAA5), Beryllium, Selenium and Barium. EPA lists 11 as archived and 1 as resolved.

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.
