Spanish Grant Subdivision standing, high SDWIS violation third
0% of 94 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%). UCMR5: UCMR5 tested, none detected.
The verdict
Spanish Grant Subdivision sits in the upper third of the sitemap cohort by violation count (94), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (333; 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. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
