Chariton Municipal Water Works standing, high SDWIS violation third
64% of 590 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 64% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #8,389 of 29,740 among systems serving 500+.
The verdict
Chariton Municipal Water Works sits in the upper third of the sitemap cohort by violation count (590), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (4,381; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 64% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
