El Jardin WSC standing, mid SDWIS violation third
24% of 41 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 24% is upper-third health share (> 23%). UCMR5: upper-third PFAS panel (> 4 compounds). Population rank #4,947 of 29,740 among systems serving 500+.
The verdict
El Jardin WSC lands in the middle third by violation volume (41), large enough for peer comparisons without matching the fleet's heaviest ledgers. Population served is large (9,423; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 24% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 8 PFAS compounds (upper-third PFAS panel (> 4 compounds)).
