The verdict
Zephyrhills City Of lands in the middle third by violation volume (69), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (29,117; 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 7 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
