The verdict

Galveston County Wcid 1 lands in the middle third by violation volume (31), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (30,399; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 26% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 4 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
