Rush Creek Mutual Water System standing, low SDWIS violation third

80% of 5 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 80% is upper-third health share (> 23%).

The verdict

Rush Creek Mutual Water System is in the lower third by violation count (5; 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 smaller (102; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 80% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
