Lan del Water District standing, low SDWIS violation third
44% of 9 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 44% is upper-third health share (> 23%). UCMR5: UCMR5 tested, none detected. Population rank #5,981 of 29,740 among systems serving 500+.
The verdict
Lan del Water District is in the lower third by violation count (9; 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 (7,302; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 44% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
