Abstract

The purpose of the study was to assess the level of contamination of soils and groundwater in the catchment area of a small river. For this purpose, the territory was zoned according to the intended purpose of the land and four categories were identified: agricultural lands, water fund lands, forest fund lands, and rural settlement lands. To assess the impact of each category on soil and water pollution, cross-sections were identified along the small river bed. The study determined physicochemical and microbiological parameters. Research results have shown that due to excessive anthropogenic load, groundwater is polluted with elements such as phosphates and nitrates. In addition, an increased level of phosphorus content is observed in the soil, and a general pattern is observed – the content of nitrogen, phosphorus, potassium, as well as the total number of soil microorganisms decreases from source to mouth.
