The nitrate-nitrogen concentration of my private drinking water is over 10 parts per million. How can I reduce the concentration?
The Environmental Protection Agency (EPA) has adopted 10 parts per million (ppm) as the maximum contaminant level for nitrate-nitrogen in public water systems. Users of private water supplies might voluntarily try to meet the EPA standard of 10 ppm. For more information on EPA standards, follow this link to their website.
