Maple Manor MHP standing, high SDWIS violation third
37 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 2% is middle-third health share (≤ 23%). UCMR5: UCMR5 tested, none detected.
The verdict
Maple Manor MHP sits in the upper third of the sitemap cohort by violation count (261), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (37; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 2% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
