The verdict

Hamilton, City Of sits in the upper third of the sitemap cohort by violation count (106), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (180; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 25% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
