Mountain West Products standing, mid SDWIS violation third

27% of 26 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 27% is upper-third health share (> 23%).

The verdict

Mountain West Products lands in the middle third by violation volume (26), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (30; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 27% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
