Tierra del Lago standing, high SDWIS violation third

The verdict
Tierra del Lago sits in the upper third of the sitemap cohort by violation count (451), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (81; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 1% (middle-third health share (≤ 23%)). No UCMR5 PFAS test appears for this system in this extract.
