Three Palms Mobilehome Park standing, mid SDWIS violation third

23% of 31 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 23% is upper-third health share (> 23%).

The verdict

Three Palms Mobilehome Park lands in the middle third by violation volume (31), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (347; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 23% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
