The verdict

City of Gretna - Sapp Bros lands in the middle third by violation volume (61), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (5,975; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 80% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
