Does Garden Street Improvement Association have drinking water violations?

Of the 12 most recent violations in EPA's records, none is health-based, and the most recent began in October 2024. The violations listed here began between October 1997 and October 2024. By type: 10 monitoring and reporting and 2 public notice, recordkeeping or other. The contaminant or rule involved most often is Total coliform bacteria (TCR) (7 of them). EPA lists 7 as archived and 5 as resolved. 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.
