There are both natural and man-made sources of nitrates in groundwater. The main source of nitrate contamination appears to be from agricultural operations, farm runoff and fertilizer usage. There also is some nitrate formed in the atmosphere by oxidation of nitrogen oxides that are emitted from power plants and internal combustion engines. One other man-made source is industrial corrosion inhibitors that have leaked into the ecosystem.
Naturally occurring nitrate can result from a combination of nitrogen and oxygen through electrical discharges (lightning). Also, nitrate is formed by Nitrobacter bacteria by oxidation of nitrites.
