Ponderosa Park Dwid 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 8% is middle-third health share (≤ 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #26,087 of 29,740 among systems serving 500+.
The verdict
Ponderosa Park Dwid sits in the upper third of the sitemap cohort by violation count (83), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (602; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 8% (middle-third health share (≤ 23%)). UCMR5 detected 6 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
