Boone County Cons PWSD 1 standing, mid SDWIS violation third

100% of 22 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 100% is upper-third health share (> 23%). UCMR5: UCMR5 tested, none detected. Population rank #2,261 of 29,740 among systems serving 500+.

The verdict

Boone County Cons PWSD 1 lands in the middle third by violation volume (22), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (24,700; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 100% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
