Vatia ASG standing, mid SDWIS violation third
0% of 48 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
Vatia ASG lands in the middle third by violation volume (48), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (460; 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.
