Willshire Village standing, high SDWIS violation third
45% of 765 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%).
The verdict
Willshire Village sits in the upper third of the sitemap cohort by violation count (765), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (405; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 45% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
