Aqua Illinois-North Maine Utilities standing, high SDWIS violation third
57% of 89 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 57% is upper-third health share (> 23%). UCMR5: UCMR5 tested, none detected. Population rank #1,845 of 29,740 among systems serving 500+.
The verdict
Aqua Illinois-North Maine Utilities sits in the upper third of the sitemap cohort by violation count (89), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (30,043; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 57% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
