The verdict
Wellsville Village Public Water lands in the middle third by violation volume (30), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (5,700; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is only 0% - almost all of this trail is monitoring or reporting. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
