Marshall County Psd 1 standing, mid SDWIS violation third

UCMR5 detected 2 PFAS compounds - lower-third PFAS panel (≤ 2 compounds). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 6% is middle-third health share (≤ 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #9,705 of 29,740 among systems serving 500+.

The verdict

Marshall County Psd 1 lands in the middle third by violation volume (51), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (3,463; 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 2 PFAS compounds (lower-third PFAS panel (≤ 2 compounds)).
