Canton standing, mid SDWIS violation third
26% of 65 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: middle-third PFAS panel (≤ 4 compounds). Population rank #3,142 of 29,740 among systems serving 500+.
The verdict
Canton lands in the middle third by violation volume (65), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (16,748; 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 detected 3 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
