Alcott School standing, high SDWIS violation third

0% of 108 recorded violations are health-based - lower-third health share (≤ 1%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 0% is lower-third health share (≤ 1%). Population rank #25,519 of 29,740 among systems serving 500+.

The verdict

Alcott School sits in the upper third of the sitemap cohort by violation count (108), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (638; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is only 0% - almost all of this trail is monitoring or reporting. No UCMR5 PFAS test appears for this system in this extract.
