The verdict
Village of Hosston Water System sits in the upper third of the sitemap cohort by violation count (493), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (729; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 60% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
