Does Hudson City have drinking water violations?
EPA's records list 9 violations for this system; 5 are health-based, and the most recent began in July 2007. The violations listed here began between March 1994 and July 2007. By type: 4 contaminant level above the legal limit, 2 public notice, recordkeeping or other, 2 monitoring and reporting and 1 required treatment not met. The contaminant or rule involved most often is Haloacetic acids (HAA5) (2 of them). EPA lists 7 as resolved and 2 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. 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.
