Columbus Municipal Utility standing, low SDWIS violation third
0% of 8 recorded violations are health-based - lower-third health share (≤ 1%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 0% is lower-third health share (≤ 1%). UCMR5: middle-third PFAS panel (≤ 4 compounds). Population rank #1,055 of 29,740 among systems serving 500+.
The verdict
Columbus Municipal Utility is in the lower third by violation count (8; 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 (51,122; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is only 0% - almost all of this trail is monitoring or reporting. UCMR5 detected 4 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
