The verdict
Middletown City PWS lands in the middle third by violation volume (61), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (51,229; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 15% (middle-third health share (≤ 23%)). UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
