Massachusetts has 859 active transient non-community water systems, 53% of the state's 1,636 active systems. 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.

Who owns and regulates The Back Eddy?

Does The Back Eddy have drinking water violations?

EPA's records list 5 violations for this system; 2 are health-based, and the most recent began in October 2011. The violations listed here began between July 2006 and October 2011. By type: 2 monitoring and reporting, 2 contaminant level above the legal limit and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 3 as archived 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. 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.
