The verdict
Archdale, City Of sits in the upper third of the sitemap cohort by violation count (127), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (12,700; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 55% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 8 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
