Model investigations of groundwater pollution by nitrogen compounds

Abstract

The pollution of ground water is an indicator of the environmental pollution and is especially susceptible to the impact of anthropogenic factors. Agriculture is general source of water pollution. The aim of the research is investigation of movement of pollution with groundwater when object of pollution is concentrated organic waste. To determine the dynamics of contaminants, twenty-one 3-metre deep piezometers were installed near the source of pollution. The level of pollution of groundwater differs from year to year, nevertheless when a concentrated source of pollution is present, it remains high. Diffusion of nitrogen combinations in groundwater depends on relief of the soil surface; the concentration of water contaminants is greater in lower areas. In early spring the process of nitrification is intensive, after 6 weeks the process of nitrification slows down and the process of denitrification intensifies.
