The verdict
Alvo, Village Of sits in the upper third of the sitemap cohort by violation count (145), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (142; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 54% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
