Dalton standing, mid SDWIS violation third

92% of 36 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 92% is upper-third health share (> 23%).

The verdict

Dalton lands in the middle third by violation volume (36), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (209; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 92% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
