Jackrabbit standing, mid SDWIS violation third
40 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 5% is middle-third health share (≤ 23%).
The verdict
Jackrabbit lands in the middle third by violation volume (62), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (40; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 5% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
