Washington City standing, high SDWIS violation third
45,865 people served (SDWIS) - larger served population (> 3,309). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 6% is middle-third health share (≤ 23%). UCMR5: UCMR5 tested, none detected. Population rank #1,203 of 29,740 among systems serving 500+.
The verdict
Washington City sits in the upper third of the sitemap cohort by violation count (201), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (45,865; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 6% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
