The verdict
Murray Hills S/D sits in the upper third of the sitemap cohort by violation count (223), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (89; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is only 0% - almost all of this trail is monitoring or reporting. No UCMR5 PFAS test appears for this system in this extract.
