Service Flow Rates (GPM)

Nitrate (NO3-) is one of the major ions in natural water. It comes into water supplies through the nitrogen cycle rather than via dissolved minerals. Natural bacteria in soil converts nitrogen into nitrate. Rain or irrigation water can carry nitrate down through the soil into groundwater.

Nitrate in drinking water occurs when septic systems, feed lots and agricultural fertilizers contaminate ground water supplies. Your drinking water may contain nitrate if your well draws from this groundwater.

Nitrate is reduced to nitrite in the human body. The U.S. EPA's MCL for nitrate is 10mg/l.

Crystal Quest Commercial Nitrate Removal Systems contain a special nitrate selective resin. Nitrate reduction is 90% to 95% and breakthrough is not affected by sodium levels. The media is regenerated by a sodium chloride brine solution.

Signs & Symptoms

Only in cases of high-level contamination will immediate signs or symptoms appear. These would be experienced most often by infants and include shortness of breath and blue coloration of the skin. Over long periods of exposure, complications of the spleen may occur. The most common way of finding out about high-level nitrates in drinking water is by the media (newspapers, TV, radio, etc.) though there are tests available to detect even low-level nitrate presence.

What Causes It?

Fertilizers are the most common sources of nitrate contamination via potassium nitrate and ammonium nitrate. Nitrates don’t bond to soil or evaporate so they are often able to sink into wells and aquifers which may serve as drinking water sources. Stream runoff and other means of groundwater contamination contribute to the majority of nitrates found in wells and water supplies.

Primary Concerns

Health risks are definitely a concern with the presence of nitrates. Excessive levels of nitrates in drinking water have caused serious illness and sometimes death. In infants, the seriousness is due to the body’s tendency to convert nitrates to nitrites, which negatively affects the oxygen-carrying capacity of the blood. Blue discolorations of the skin accompanied by shortness of breath are diagnostic findings of this phenomenon. Long-term exposure is found to cause splenic hemorrhaging, leading to diuresis.


Ion Exchange and Reverse Osmosis are two EPA-approved methods of nitrate removal. The responsibility to detect nitrate levels and implement solutions is usually on the shoulders of your local water authority. However, those who draw drinking water from wells and other unsupervised sources should contact local water authorities or their local water professionals for proper tests and for available solutions in cases where high nitrate levels are found.
