Remove Nitrate from Your Drinking Water 


Nitrate (NO3) comes into water supplies through the nitrogen cycle rather than via dissolved minerals. It is one of the major ions in natural waters. Most nitrate that occurs in drinking water is the result of contamination of groundwater supplies by septic systems, feedlots, and agricultural fertilizers. Natural bacteria in the soil can convert nitrogen into nitrate. Rain or irrigation water can carry nitrate down through the soil into groundwater. Your drinking water may contain nitrate if your well draws from this groundwater. The regeneration process should be done every 20 to 30 days depending on level of nitrate. Nitrate is reduced to nitrite in the body. Nitrate in drinking water supplies may reduce the oxygen-carrying capacity of the blood (cyanosis) if ingested in sufficient amounts by infants under 6 months of age. This could cause a disease called methemoglobinemia, or “blue baby” syndrome. The EPA has established a maximum contaminant level (MCL) for nitrate at 10 mg/1 (PPM), measured as N. Unlike coliform or other types of bacteria, boiling the water will actually INCREASE the amount of nitrate remaining in the water, increasing the danger to infants.


Water flows through a 20” sediment cartridge that removes sediment, silt, sand, and dirt.


Water flows through a 20" solid carbon cartridge for removing volatile organic carbon compounds (VOC's), & any remaining insecticides, pesticides and industrial solvents.

Nitrate Removal Water Filter

Water flows through a Nitrate reducing mineral tank and brine water conditioner. In addition, we add our media, ERA® 6500 & 9500 to prevent bacteria growth.

Important to Know

Pinholes or rust may occur on stainless steel tanks in environments with high humidity, when salt is present or if condensation remains on tank without being routinely wiped down. If your system will be exposed to one of these factors or you are unable to perform the needed maintenance, we recommend a fiberglass tank.
