The verdict
Harrisburg, Town Of lands in the middle third by violation volume (73), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (20,549; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 36% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 5 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
