Copper Trace S/D standing, low SDWIS violation third
100% of 6 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 100% is upper-third health share (> 23%). UCMR5: UCMR5 tested, none detected.
The verdict
Copper Trace S/D is in the lower third by violation count (6; 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 (66; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 100% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
