The verdict
Colchester Fire District 2 lands in the middle third by violation volume (46), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (8,300; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 11% (middle-third health share (≤ 23%)). UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
