The verdict

Housatonic Meadows/Riverside lands in the middle third by violation volume (31), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (33; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 39% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
