Columbine Cg standing, mid SDWIS violation third

55% of 38 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 55% is upper-third health share (> 23%).

The verdict

Columbine Cg lands in the middle third by violation volume (38), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (376; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 55% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
