Cedar Creek Mobilehome Park 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 13% is middle-third health share (≤ 23%).

The verdict

Cedar Creek Mobilehome Park 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 13% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
