Blissfield standing, mid SDWIS violation third
36% of 59 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 36% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #9,996 of 29,740 among systems serving 500+.
The verdict
Blissfield lands in the middle third by violation volume (59), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is mid-pack at 3,276 (mid served population (≤ 3,309)). Health-based share is 36% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
