Does Pittsfield Aqueduct have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in April 2019. The violations listed here began between January 1995 and April 2019. By type: 12 monitoring and reporting. The contaminants or rules involved are Surface Water Treatment Rule, Long Term 2 Enhanced Surface Water Treatment Rule, Haloacetic acids (HAA5) and Total trihalomethanes (TTHM). EPA lists 11 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.
