The verdict
Mvwa - Mohawk Valley Water Authority lands in the middle third by violation volume (53), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (126,250; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 55% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
