Hastings standing, mid SDWIS violation third
83% of 24 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 83% is upper-third health share (> 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #2,404 of 29,740 among systems serving 500+.
The verdict
Hastings lands in the middle third by violation volume (24), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (23,222; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 83% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 7 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
