Paxton Water Department standing, mid SDWIS violation third
31% of 49 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 31% is upper-third health share (> 23%). UCMR5: middle-third PFAS panel (≤ 4 compounds). Population rank #8,457 of 29,740 among systems serving 500+.
The verdict
Paxton Water Department lands in the middle third by violation volume (49), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (4,300; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 31% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 3 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
