Yeshiva Farm Settlement standing, high SDWIS violation third
UCMR5 detected 10 PFAS compounds - upper-third PFAS panel (> 4 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 7% is middle-third health share (≤ 23%). UCMR5: upper-third PFAS panel (> 4 compounds).
The verdict
Yeshiva Farm Settlement sits in the upper third of the sitemap cohort by violation count (206), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (300; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 7% (middle-third health share (≤ 23%)). UCMR5 detected 10 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
