The verdict
Rio Vista (2 Wps) lands in the middle third by violation volume (51), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (400; 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.
