Current state of the problem of groundwater contamination in Belarus nitrogen compounds and solutions
Given special attention to the problem of nitrate pollution in groundwater of Brest region. The most intensive pollution covers a thickness of 10-15 m, which is very important for rural areas and home gardens, but often and at depths of 40-50 m are recorded nitrate concentrations exceeding the maximum permissible level (45 mg/l content nitrates). Considered known in the field of water treatment methods for removal of ammonium nitrogen, nitrate and nitrite from natural water. Results of experimental researches on determination of exchange capacity of ion exchangers involved in the process of cleaning water from nitrates by ion exchange for drinking water.
