South Kern Mutual Water Company standing, mid SDWIS violation third

49% of 37 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 49% is upper-third health share (> 23%).

The verdict

South Kern Mutual Water Company lands in the middle third by violation volume (37), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is smaller (32; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 49% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
