The verdict

Cromwell Fire District Water Department sits in the upper third of the sitemap cohort by violation count (232), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (14,316; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 1% (middle-third health share (≤ 23%)). UCMR5 detected 2 PFAS compounds (lower-third PFAS panel (≤ 2 compounds)).
