Does Hillcrest Water District have drinking water violations?
EPA's records list 5 violations for this system; 3 are health-based, and the most recent began in April 2010. The violations listed here began between January 1994 and April 2010. By type: 3 contaminant level above the legal limit and 2 monitoring and reporting. The contaminants or rules involved are Tetrachloroethylene, cis-1,2-Dichloroethylene, Trichloroethylene and Lead and Copper Rule. EPA lists 4 as resolved and 1 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.
