Grand Rivers Water System 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 17% is middle-third health share (≤ 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #8,908 of 29,740 among systems serving 500+.
The verdict
Grand Rivers Water System lands in the middle third by violation volume (59), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (3,980; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 17% (middle-third health share (≤ 23%)). UCMR5 detected 2 PFAS compounds (lower-third PFAS panel (≤ 2 compounds)).
