The verdict
Franklin Grove lands in the middle third by violation volume (38), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (896; 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.
