North Holbrook WC standing, high SDWIS violation third
72% of 363 recorded violations are health-based - upper-third health share (> 23%). Corpus terciles use 29,740 systems serving 500+ (the sitemap cohort). Health-based share 72% is upper-third health share (> 23%). UCMR5: UCMR5 tested, none detected.
The verdict
North Holbrook WC sits in the upper third of the sitemap cohort by violation count (363), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is smaller (58; smaller served population (≤ 999)), so each violation row represents a compact service footprint. Health-based share is 72% - most of this ledger is MCL or treatment-technique exceedance. UCMR5 tested this system and reported no PFAS above the minimum reporting level.
