Alpine Pacific Utilities standing, high SDWIS violation third

0% of 104 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%).

The verdict

Alpine Pacific Utilities sits in the upper third of the sitemap cohort by violation count (104), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (270; 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.
