Ellenville (Village) Water Dis standing, high SDWIS violation third
4,300 people served (SDWIS) - larger served population (> 3,309). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 9% is middle-third health share (≤ 23%). UCMR5: UCMR5 tested, none detected. Population rank #8,464 of 29,740 among systems serving 500+.
The verdict
Ellenville (Village) Water Dis sits in the upper third of the sitemap cohort by violation count (235), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (4,300; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 9% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.

How many violations vs. how serious, among peer systems
Ellenville (Village) Water Dis plotted against 29 peer public water systems (500+ people served), by total violation count (x) and the share of those violations that are health-based (y). The crosshair sits at this sample's own median on each axis. A high violation count does not automatically mean a serious record: most monitoring and reporting violations are minor, not health-based.
