Newport-City Of standing, high SDWIS violation third
45% of 134 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 45% is upper-third health share (> 23%). UCMR5: middle-third PFAS panel (≤ 4 compounds). Population rank #1,307 of 29,740 among systems serving 500+.
The verdict
Newport-City Of sits in the upper third of the sitemap cohort by violation count (134), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (42,155; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 45% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 detected 3 PFAS compounds (middle-third PFAS panel (≤ 4 compounds)).
