FAQ

Can nitrate be removed from a whole house well system?

It can, but many households choose point-of-use treatment for drinking water first because whole-house nitrate treatment requires careful design and maintenance.

Can adults drink water with nitrate at 20 mg/L?

It is above the drinking water limit. Ask local health officials or a clinician for household-specific guidance, especially for pregnancy or medical conditions.
