Bedford County U.d. standing, high SDWIS violation third
60% of 190 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 60% is upper-third health share (> 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #2,435 of 29,740 among systems serving 500+.
The verdict
Bedford County U.d. sits in the upper third of the sitemap cohort by violation count (190), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (22,908; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 60% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 5 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
