Energy Dept of/300 Area standing, low SDWIS violation third
100% of 10 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%). Population rank #26,592 of 29,740 among systems serving 500+.
The verdict
Energy Dept of/300 Area is in the lower third by violation count (10; 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 (600; 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. No UCMR5 PFAS test appears for this system in this extract.
