The verdict
Cuba Water System sits in the upper third of the sitemap cohort by violation count (511), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is mid-pack at 1,789 (mid served population (≤ 3,309)). Health-based share is 39% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
