Ocwa standing, low SDWIS violation third
57% of 7 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 57% is upper-third health share (> 23%). UCMR5: lower-third PFAS panel (≤ 2 compounds). Population rank #96 of 29,740 among systems serving 500+.
The verdict
Ocwa is in the lower third by violation count (7; lower-third violation load (≤ 21 violations)). A low count does not mean the system is unmonitored - monitoring and reporting violations still appear in SDWIS. Population served is large (350,000; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 57% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 1 PFAS compound (lower-third PFAS panel (≤ 2 compounds)).
