Nitrate and nitrite are soluble compounds containing nitrogen and oxygen. Nitrate (NO3-) is more stable than nitrite (NO2-). This means nitrite easily changes into nitrate in groundwater and the results of a nitrate plus nitrite test are almost always predominantly nitrate. Because nitrate salts are very soluble, nitrate is highly mobile in soil and migrates readily to the water table when present in excess of the amount utilized by plants as an essential nutrient. Under anaerobic conditions, nitrate may be degraded to nitrite or denitrified. Biological activity in the soil is very important in determining the ultimate fate of nitrate.
