Naples Water Dept standing, mid SDWIS violation third
UCMR5 detected 5 PFAS compounds - upper-third PFAS panel (> 4 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 17% is middle-third health share (≤ 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #621 of 29,740 among systems serving 500+.
The verdict
Naples Water Dept lands in the middle third by violation volume (46), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (82,000; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 17% (middle-third health share (≤ 23%)). UCMR5 detected 5 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
