The ecological capacity assessment of the Ilek River with boron pollution
AbstractIn the article is provided an analysis of the pollution identification sources of underground andsurface water of the Ilek river valley. The problem of the boron pollution of the Ilek River is very acute,because the boron element is transported along the river and is stored in the silt of the Aktobe reservoir,which is a recreational resource and source of water supply in Aktobe. The great dynamism of boronleads to the fact that when roiling during releases from the reservoir boron falls into the lower course ofthe Ilek river, causing damage to river organisms (teratogenic effect) and the population, adversely affecting heredity. Boron pollution of the Aktyubinsk reservoir is largely determined by the self-cleaningability of the Ilek River, depending on the volume and concentration of polluted groundwater discharging into the river. In this work, the old sludge collector role in the pollution of the surface water of theIlek River and the Aktobe reservoir is established. The authors carried out calculations to identify thezone of thinning-out of groundwater into the Ilek River, determined the amount of boron flowing intothe Ilek River in these zones. Calculations were made of the mass taken out of the boron storage pond;the self-purification processes of the Ilek River were estimated based on the regression model of boronconcentration dilution when the ground water was wedged out by the river. The predictive estimate wasmade of the time to reach the concentration of boron equal to the MPC for drinking water supply at theAlga 2 regime station.Key words: groundwater, surface water, pollution, boron, self-cleaning process, regression dilutionmodel, ecological capacity
