Does Devens Massdevelopment have drinking water violations?
Of the 12 most recent violations in EPA's records, one is health-based, and the most recent began in August 2021. The violations listed here began between April 1998 and August 2021. By type: 10 monitoring and reporting, 1 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminants or rules involved are Haloacetic acids (HAA5), Total trihalomethanes (TTHM), Total coliform bacteria (TCR) and Consumer Confidence Rule. EPA lists 8 as archived and 4 as resolved. 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. 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.
