Ironside Water District Inc standing, high SDWIS violation third

70% of 188 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 70% is upper-third health share (> 23%).

The verdict

Ironside Water District Inc sits in the upper third of the sitemap cohort by violation count (188), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (392; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 70% - most of this ledger is MCL or treatment-technique exceedance. No UCMR5 PFAS test appears for this system in this extract.
