Highridge Water Auth standing, high SDWIS violation third
UCMR5 detected 6 PFAS compounds - upper-third PFAS panel (> 4 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 14% is middle-third health share (≤ 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #3,276 of 29,740 among systems serving 500+.
The verdict
Highridge Water Auth sits in the upper third of the sitemap cohort by violation count (249), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (16,000; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 14% (middle-third health share (≤ 23%)). UCMR5 detected 6 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
