Does Center City have drinking water violations?
EPA's records list 7 violations for this system; 3 are health-based, and the most recent began in January 2024. The violations listed here began between October 1991 and January 2024. By type: 3 contaminant level above the legal limit, 3 monitoring and reporting and 1 monitoring. The contaminant or rule involved most often is Total coliform bacteria (TCR) (5 of them). EPA lists 4 as resolved and 3 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.
