ECOLOGICAL CONDITION OF THE SEROVKA RIVER IN THE TOWN OF CHEREPOVETS
In addition to large rivers on the territory of Russia there are about 2.5 million small rivers, of which only 5% of the water volume is used for the needs of the population and household complex, which is due to its low quality due to anthropogenic eutrophication and pollution. Such an object is a small river Serovka. The environmental condition of the Serovka River flowing through the city of Cherepovets, Vologda Region, has been assessed. Several methods have been used in the long-term study of water quality and the territory adjacent to the river: geographical mapping of the area, observations of the state of the water body and the adjacent territory, organoleptic and chemical analysis of water [2], bio-testing with cress salad [3]. A schematic map of the river and its adjacent territory has been developed. Taken and analyzed in three-fold repetition of 43 water samples. The study revealed the types of pollutants and places of unauthorized runoff into the Serovka River, a large amount of debris in the water and on its coast.
