Nitrogen level? N2? Maybe if you mean nitrite or nitrate then this might be done by:
Sulfanilic acid and N-(1-Naphthyl)-ethylendiamine hydrochloride called Saltzmann reagent
To determine the nitrate level one reduces the nitrate by e.g. Zn/HCl before of the test
NItrogen is too inreactive to have a simple chemical reaction in water.
