Waterford Water/Sewer Association 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 8% is middle-third health share (≤ 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #23,077 of 29,740 among systems serving 500+.
The verdict
Waterford Water/Sewer Association sits in the upper third of the sitemap cohort by violation count (127), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (770; 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 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
