Assessment of the hydro-geochemical situation in Alga region (Aktobe, Kazakhstan) based on component analysis

The article attempts to realize the informational capabilities of the multidimensional component analysis model, one of the purposes of which is to form hypotheses to test numerous hypotheses put forward to identify the sources and pathways of boron element entering into the underground and surface water of the Ilek River valley. Nowadays, the relevance of this problem is being stimulated by the development of the pollution process - a manifestation of the impact on the river of those sources that were not previously recorded in the state monitoring of the quality of the surface waters of this river. As a result of processing the monitoring data for different periods of time, the processes of formation of the chemical composition of groundwater of the Ilek River valley were revealed, which confirmed the presence of various sources of contamination with their boron, in addition, temporal and spatial aspects of the intensity of these processes were established.
