Aqua Ohio - Aurora E standing, mid SDWIS violation third
766 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 5% is middle-third health share (≤ 23%). UCMR5: UCMR5 tested, none detected. Population rank #23,110 of 29,740 among systems serving 500+.
The verdict
Aqua Ohio - Aurora E lands in the middle third by violation volume (58), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (766; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 5% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
