The verdict
Ranchero Estates sits in the upper third of the sitemap cohort by violation count (161), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (105; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 2% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
