The verdict

Laurens Cpw (Sc3010001) lands in the middle third by violation volume (40), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (13,902; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 20% (middle-third health share (≤ 23%)). UCMR5 detected 3 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
