The verdict

Holland TN Sanitary Dist lands in the middle third by violation volume (71), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (495; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 48% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
