The verdict

Wall Twp Water Dept lands in the middle third by violation volume (52), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (26,000; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 12% (middle-third health share (≤ 23%)). UCMR5 detected 4 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
