The verdict

Arkansas City Waterworks lands in the middle third by violation volume (48), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (376; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 85% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
