The purpose. To study the content of nitrogen-bearing joints in well water within the limits of Chernivtsi oblast for 2013-2014 and to analyze their link with some agrochemical and agroecological indexes. Methods. Field, laboratory (potentiometric – for determination of ions of NO3 — with the use of nitrates-meter N-401; photocolorimetric – for determination of density of NO2 and NН4 with the use of FEK KFK-3), statistical. Results. Nitrate pollution is fixed of the decentralized water service, and also the heightened content of nitrites. By means of the method of principal components it is shown that densities of NO3 — and NН4 + form joint association with some agrochemical and agroecological indexes. It is fixed basin differences of probed joints within the limits of terrain of Chernivtsi oblast. Conclusions. It is determined that drinking water of Northern Bukovyna belongs to the class of pure and quite pure waters and has congenial ecological state. However within the limits of these characteristics there were certain changes in indexes of density of nitrogen-bearing joints.
