Formation of the Chemical Composition of Water of the Karymskaya River under the Influence of Hydrothermal and Volcanic Activity (Kamchatka Peninsula)

In this paper, on the example of the Karymsky volcanic center, we assess the degree of influence of volcanic and hydrothermal activity on the chemical composition of river waters; we show the volumes of macro and microelements from the Karymskaya River to the Pacific Ocean. The quality of river waters was assessed according to the standards defined for waters of drinking / cultural and household use and of fishery significance. It is shown that the formation of the ion load of river water occurs mainly due to the inflow of thermal waters, as well as due to the water-soluble complexes of ashes of the Karymsky volcano eruptions, which enter the river catchment area. The annual volume of dissolved matter carried by the river into the Kronotsky Bay of the Pacific Ocean is more than 90 kilotons.
