Does Plandome (V) have drinking water violations?
EPA's records list 8 violations for this system; 4 are health-based, and the most recent began in July 2008. The violations listed here began between September 1993 and July 2008. By type: 4 public notice, recordkeeping or other and 4 contaminant level above the legal limit. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 5 as resolved and 3 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.
