Аннотация: Small, medium and large rivers are adversely affected by wastewater discharges by water user organizations. Although this is a slight excess of the permissible concentration of pollutants, but, as is well known, large results from small. So, it is here: every enterprise that discharges waste water with elevations at permissible established concentrations reduces the ability of rivers to clean themselves. The purpose of the study is to determine the level of pollution p. Dubna, Moscow region. In this study, a general description of the p. Dubna on the basis of hydrological indicators and background concentrations provided by the Central UGMS. To assess the nature of water pollution r. Dubna, considering the contribution of enterprises, a section of the river from the mouth to the confluence of the r. Kunya Moscow region. The level of ability to self-purification was identified based on the distribution of pollutants in the groups of the limiting indicator of hazard. The organoleptic group includes suspended solids; fishery - oil products; sanitary - BODfull, phosphates; sanitary toxicological - chlorides, sulfates, chromium +3; To toxicological - total iron, ammonium ion, ion nitrite, ion nitrate, copper, nickel, chromium +6, zinc. After analyzing the calculations for each substance, it was found that the self-cleaning ability p. Dubna in the analyzed area has been exhausted. Since there are significant exceedances for all pollutants emitted, a standard of permissible discharge was established for the MPC (the Dubna river is a river of fisheries value). The standard of permissible discharge proposed by us for MPС should reduce the anthropogenic load on the waters of the river Dubna.
