Does Nuevo Water Company have drinking water violations?
EPA's records list 9 violations for this system; 6 are health-based, and the most recent began in April 2019. The violations listed here began between January 1985 and April 2019. By type: 6 contaminant level above the legal limit, 2 monitoring and reporting and 1 public notice, recordkeeping or other. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (5 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.
