We examine some special features inherent in the formation of resources and chemical composition of the surface waters in the Eravninskaya depression. It is shown that dislocations with a break in continuity have a considerable influence on the hydrochemical behavior of the lakes. Lake Bol. Surkhebt, Lake Gunda and Lake Mal. Eravnoe will experience the greatest level of exposure to pollution caused by the operation of the Ozyornoe polymetal deposit.Keywords: lakes, surface runoff, subsurface flow, faults, technogenesis, pollution.
