Clermont Public Water System standing, mid SDWIS violation third
133,059 people served (SDWIS) - larger served population (> 3,309). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 15% is middle-third health share (≤ 23%). UCMR5: middle-third PFAS panel (≤ 4 compounds). Population rank #336 of 29,740 among systems serving 500+.
The verdict
Clermont Public Water System lands in the middle third by violation volume (62), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (133,059; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 15% (middle-third health share (≤ 23%)). UCMR5 detected 3 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
