Does Border City Water District have drinking water violations?
Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in January 2020. The violations listed here began between February 1995 and January 2020. By type: 6 public notice, recordkeeping or other, 5 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (2 of them). EPA lists 10 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.
