Simpson County Water District standing, mid SDWIS violation third
49% of 35 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 49% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #5,160 of 29,740 among systems serving 500+.
The verdict
Simpson County Water District lands in the middle third by violation volume (35), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (8,946; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 49% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
