The verdict
El Sauz WSC sits in the upper third of the sitemap cohort by violation count (278), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is mid-pack at 2,223 (mid served population (≤ 3,309)). Health-based share is 33% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
