Bethel Water Dept standing, high SDWIS violation third
9,507 people served (SDWIS) - larger served population (> 3,309). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 19% is middle-third health share (≤ 23%). UCMR5: middle-third PFAS panel (≤ 4 compounds). Population rank #4,900 of 29,740 among systems serving 500+.
The verdict
Bethel Water Dept sits in the upper third of the sitemap cohort by violation count (248), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (9,507; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 19% (middle-third health share (≤ 23%)). UCMR5 detected 3 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
