The verdict
Demopolis Water Works and Sewer Board sits in the upper third of the sitemap cohort by violation count (120), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (10,530; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 11% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
