Hesperia standing, mid SDWIS violation third
25% of 32 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 25% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #20,311 of 29,740 among systems serving 500+.
The verdict
Hesperia lands in the middle third by violation volume (32), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (954; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 25% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 2 PFAS compounds (lower-third PFAS panel (≤ 2 compounds)).
