The verdict
Upper Saucon Twp Water Supply sits in the upper third of the sitemap cohort by violation count (620), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (7,300; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 1% (middle-third health share (≤ 23%)). UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
