The verdict
Guy Waterworks lands in the middle third by violation volume (48), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is mid-pack at 2,438 (mid served population (≤ 3,309)). Health-based share is 40% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
