The verdict
Gloucester Public Utility Division sits in the upper third of the sitemap cohort by violation count (171), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (37,440; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 3% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
