Neptune Beach standing, mid SDWIS violation third

7,270 people served (SDWIS) - larger served population (> 3,309). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 8% is middle-third health share (≤ 23%). UCMR5: UCMR5 tested, none detected. Population rank #6,000 of 29,740 among systems serving 500+.

The verdict

Neptune Beach 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 (7,270; 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.
