M and C Childrens Learning Pl standing, high SDWIS violation third

75 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 3% is middle-third health share (≤ 23%).

The verdict

M and C Childrens Learning Pl sits in the upper third of the sitemap cohort by violation count (575), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (75; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 3% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
