The verdict
Mingo Junction PWS sits in the upper third of the sitemap cohort by violation count (156), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (3,350; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 8% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
