Wright State University standing, mid SDWIS violation third
26% of 47 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 26% is upper-third health share (> 23%). UCMR5: UCMR5 tested, none detected. Population rank #5,159 of 29,740 among systems serving 500+.
The verdict
Wright State University lands in the middle third by violation volume (47), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (8,948; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 26% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
