Lillington Water System standing, mid SDWIS violation third
UCMR5 detected 8 PFAS compounds - upper-third PFAS panel (> 4 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 6% is middle-third health share (≤ 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #9,101 of 29,740 among systems serving 500+.
The verdict
Lillington Water System lands in the middle third by violation volume (36), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (3,847; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 6% (middle-third health share (≤ 23%)). UCMR5 detected 8 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
