Groundwater means the system draws its water from wells or springs fed by underground aquifers. 1,354 Massachusetts systems (83%) list groundwater as their primary source.

Does Granby Housing Authority have drinking water violations?
Of the 12 most recent violations in EPA's records, 3 are health-based, and the most recent began in June 2015. The violations listed here began between April 1999 and June 2015. By type: 9 monitoring and reporting and 3 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 8 as archived, 2 as addressed and 2 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. Addressed means the violation is not resolved or archived and is covered by formal enforcement. 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.
