Caldwell Village PWS standing, high SDWIS violation third
40% of 95 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 40% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #9,950 of 29,740 among systems serving 500+.
The verdict
Caldwell Village PWS sits in the upper third of the sitemap cohort by violation count (95), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is mid-pack at 3,300 (mid served population (≤ 3,309)). Health-based share is 40% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
