Nanty Glo Water Auth standing, high SDWIS violation third
UCMR5 detected 1 PFAS compound - lower-third PFAS panel (≤ 2 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 16% is middle-third health share (≤ 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #10,263 of 29,740 among systems serving 500+.
The verdict
Nanty Glo Water Auth sits in the upper third of the sitemap cohort by violation count (466), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is mid-pack at 3,152 (mid served population (≤ 3,309)). Health-based share is 16% (middle-third health share (≤ 23%)). UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
