Trussworks Inc standing, mid SDWIS violation third

38% of 42 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 38% is upper-third health share (> 23%).

The verdict

Trussworks Inc lands in the middle third by violation volume (42), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (50; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 38% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
