The verdict
City of Lawrence Utilities lands in the middle third by violation volume (38), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (49,000; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 18% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
