The verdict
Toho Water Authority Eastern sits in the upper third of the sitemap cohort by violation count (164), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is large (110,102; larger served population (> 3,309)), so household exposure scale sits behind the violation mix. Health-based share is 7% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
