This scientific article is devoted to the problem of pollution of the Aktobe basin with boron by thewaters of the Ilek River, which drains contaminated groundwater. In connection with not full implementation of the decisions taken to reduce the concentration of pollutants, in particular boron, the problemof groundwater pollution is exacerbated. The monitoring datas fix the increased level of pollution. Initiative field studies and the results of the determination of sampling samples showed an excess of thresholdlimit value of boron both in the zone of the old sludge accumulator and in the Aktobe basin. To justifythe need to develop and implement a qualitatively new approach to the solution of the problem ofgroundwater contamination in the Ilek river valley and the Aktobe Basin, boron made estimates for thetopographic and hydrogeological, combined with the technical solutions, the feasibility study, maps. It isshown that now the front of groundwater pollution from the industrial site and the new sludge collectorhas approached the river, and therefore the technical solution of the feasibility study for the second section no longer corresponds to reality. The dynamics of the pollution processes of the Ilek River in the oldsludge accumulator zone is analyzed. Based on the regression model, a forecast is made of the changesin boron content in the right bank of the Ilek River. It is shown that the technical feasibility study on thefirst site requires a revision.As a new approach to solving the problem, it is proposed to develop a system from a constantlyoperating model of geo-filtration and a model of turbulent macro diffusion combined with it. Mappingizoconcentrate of boron and other pollutants of groundwater will provide an opportunity to considerthem from the standpoint of alternative environmental technologies, for example, as the basis of boronfertilizers.Key words: ground water, pollution, boron, basin, feasibility study.
