On paper this system is compliant, but the EPA record shows 2 violations — mostly missed testing or reporting. What isn't measured can't be caught.
The Lead & Copper Rule requires utilities to test water at customer taps for lead and copper — metals that enter water from pipes and plumbing, not the source. Lead harms brain development in children; no level is considered safe.

Health guidelines from independent scientists are often stricter. Results vary by home, plumbing and date.
NSF-58 certified under-sink RO — the only tech that broadly removes dissolved contaminants at the tap.
NSF-42 whole-house carbon cuts chlorine, chloramine and the pool-water taste.
