Does Ridgewood Ledges Water Association have drinking water violations?
EPA's records list 9 violations for this system; 2 are health-based, and the most recent began in March 2006. The violations listed here began between June 1977 and March 2006. By type: 6 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) (6 of them). EPA lists 6 as archived and 3 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.
