Cuba standing, high SDWIS violation third
29% of 122 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 29% is upper-third health share (> 23%). Population rank #18,056 of 29,740 among systems serving 500+.
The verdict
Cuba sits in the upper third of the sitemap cohort by violation count (122), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is mid-pack at 1,184 (mid served population (≤ 3,309)). Health-based share is 29% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
