Wilmington WD standing, mid SDWIS violation third
29% of 35 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 29% is upper-third health share (> 23%). Population rank #20,046 of 29,740 among systems serving 500+.
The verdict
Wilmington WD lands in the middle third by violation volume (35), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (980; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 29% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
