The verdict
Hdma - Benton RD PWS lands in the middle third by violation volume (63), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (7,600; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is only 0% - almost all of this trail is monitoring or reporting. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
