Indiana American Water - Warsaw standing, high 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 10% is middle-third health share (≤ 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #3,699 of 29,740 among systems serving 500+.
The verdict
Indiana American Water - Warsaw sits in the upper third of the sitemap cohort by violation count (87), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (13,835; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 10% (middle-third health share (≤ 23%)). UCMR5 detected 2 PFAS compounds (lower-third PFAS panel (≤ 2 compounds)).
