Stillings Grant standing, mid SDWIS violation third

61% of 28 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 61% is upper-third health share (> 23%).

The verdict

Stillings Grant lands in the middle third by violation volume (28), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (141; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 61% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
