Alexander Water District standing, mid SDWIS violation third
71% of 34 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 71% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds).
The verdict
Alexander Water District lands in the middle third by violation volume (34), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (442; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 71% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
