Science Hill Water Works standing, high SDWIS violation third
5,940 people served (SDWIS) - larger served population (> 3,309). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 11% is middle-third health share (≤ 23%). UCMR5: UCMR5 tested, none detected. Population rank #6,891 of 29,740 among systems serving 500+.
The verdict
Science Hill Water Works sits in the upper third of the sitemap cohort by violation count (105), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (5,940; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 11% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
