This nitrogen is usually in the form of nitrate. [9] The nitrate seeps through the soil and gets into the ground water through agricultural practices such as tile drainage, which eventually makes its way into the surface waters. [10] Nitrate concentration can be dangerous passed a certain level.

Nitrate levels above 10 mg/L (10 ppm) in groundwater can cause 'blue baby syndrome' (acquired methemoglobinemia). [84] The nutrients, especially nitrates, in fertilizers can cause problems for natural habitats and for human health if they are washed off soil into watercourses or leached through soil into groundwater. [ 85 ]
Lastly, ammonia, the product of the second reduction reaction, which reduces nitrate and produces nitrogen gas and ammonia, is readily adsorbed on clay mineral surfaces and protected from bacteria. This has been proposed to explain lower-than-expected C/N signatures of organic carbon in sediments undergoing post-depositional diagenesis. [6]
