Winchester Water System standing, high SDWIS violation third
39% of 98 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 39% is upper-third health share (> 23%). UCMR5: UCMR5 tested, none detected. Population rank #2,243 of 29,740 among systems serving 500+.
The verdict
Winchester Water System sits in the upper third of the sitemap cohort by violation count (98), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (24,899; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 39% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
