Sevryukova The article presents the results of ecological monitoring of the state of the Mokraya Mechetok River, located on the territory of the Volgograd Region. During the period from March 2017 to February 2018, a complex of studies was conducted in field and laboratory conditions. The organoleptic characteristics of water, the amount of dissolved oxygen in the body of water, the pH, the dry residue and bioindication parameters were estimated: the number of plants and microorganisms. Based on the dynamics of mineralization of water from March to November 2017, data on the quantitative composition of microorganisms (Synedra ulna, Diatoma mesodon, Spirogyra) from May to July 2017, changes in the acid-base balance from 7,8 to 11,0, measured during measurements in March, July, September, 2017, the river Mokraya Mechetka can be attributed to slightly polluted water reservoirs.
