The verdict
Muskingum County Water - SE lands in the middle third by violation volume (35), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (21,540; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 37% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
