Big Sandy Water District standing, high SDWIS violation third
55% of 193 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 55% is upper-third health share (> 23%). UCMR5: middle-third PFAS panel (≤ 4 compounds). Population rank #3,846 of 29,740 among systems serving 500+.
The verdict
Big Sandy Water District sits in the upper third of the sitemap cohort by violation count (193), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (13,044; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 55% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 3 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
