Does Colden Water District #1 have drinking water violations?
EPA's records list 10 violations for this system; none is health-based, and the most recent began in October 2023. The violations listed here began between January 2007 and October 2023. By type: 9 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total trihalomethanes (TTHM) (3 of them). EPA lists 9 as resolved and 1 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.
