The verdict
South Hero Fire District 4 sits in the upper third of the sitemap cohort by violation count (389), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (760; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 16% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
