Eufaula PWA standing, high SDWIS violation third
76% of 1,620 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 76% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #11,198 of 29,740 among systems serving 500+.
The verdict
Eufaula PWA sits in the upper third of the sitemap cohort by violation count (1,620), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is mid-pack at 2,766 (mid served population (≤ 3,309)). Health-based share is 76% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
