Does Galesburg East Koa have drinking water violations?
EPA's records list 9 violations for this system; 2 are health-based, and the most recent began in July 2022. The violations listed here began between July 1984 and July 2022. By type: 7 monitoring and reporting and 2 required treatment not met. The contaminant or rule involved most often is Total coliform bacteria (TCR) (4 of them). EPA lists 5 as resolved and 4 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.
