The verdict

Greenville Water (2310001) lands in the middle third by violation volume (40), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (396,265; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 50% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
