The verdict
Moriarty Water System sits in the upper third of the sitemap cohort by violation count (110), so the tables below sample a dense compliance trail rather than a near-clean ledger. Population served is mid-pack at 2,825 (mid served population (≤ 3,309)). Health-based share is 15% (middle-third health share (≤ 23%)). UCMR5 tested this system and reported no PFAS above the minimum reporting level.
