The verdict
Parker, City of Water System lands in the middle third by violation volume (34), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (4,317; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 41% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
