Retrospective analysis of acid-alkaline conditions of ground water within the Perm area

The indicator of hydrogen рН ions concentration is an important parameter of water environment that determines a variety of processes of chemical components migration. According to long-term regime study on chemical composition of underground water in zone of the active water exchange in the Perm urban area conducted by the Dynamic Geology and Hydrogeology Department of the Perm State University, the acid-alkaline conditions were outlined, reasons of their change were established, and the role of technogenic factors was estimated.
