43% of 103 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort).

The verdict
Canton, City Of sits in the upper third of the sitemap cohort by violation count (103), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (699; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 43% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
