Shelley City Of standing, mid SDWIS violation third
48% of 33 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 48% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #8,350 of 29,740 among systems serving 500+.
The verdict
Shelley City Of lands in the middle third by violation volume (33), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (4,409; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 48% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
