The verdict
Davidsons Countryside Cpgd lands in the middle third by violation volume (24), large enough for peer comparisons without matching the fleet's heaviest ledgers.

Health-based share is 33% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
