Fort Wayne - 3 Rivers Filtration Plant standing, mid SDWIS violation third
38% of 37 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 38% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #142 of 29,740 among systems serving 500+.
The verdict
Fort Wayne - 3 Rivers Filtration Plant lands in the middle third by violation volume (37), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (269,994; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 38% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 2 PFAS compounds (lower-third PFAS panel (≤ 2 compounds)).
