Lake Canyon Mutual Water Company standing, high SDWIS violation third
156 people served (SDWIS) - smaller served population (≤ 999). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 19% is middle-third health share (≤ 23%).
The verdict
Lake Canyon Mutual Water Company sits in the upper third of the sitemap cohort by violation count (115), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (156; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 19% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
