The verdict
Beardstown 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 (5,951; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 8% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
