The verdict
Marlboro Township Water Utility Division sits in the upper third of the sitemap cohort by violation count (115), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (29,480; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 11% (middle-third health share (≤ 23%)). UCMR5 detected 3 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
