The verdict
Bellbrook Water Works lands in the middle third by violation volume (37), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (9,475; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 22% (middle-third health share (≤ 23%)). UCMR5 detected 3 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
