The article analyzes hydrochemical characteristics of bog water studied by scientific experts in this sphere: the Kalinin Polytechnical Institute, the State Hydrological Institute and the Tomsk Polytechnic University. The beneficial effect is mentioned, and the deficiencies are pointed at: the lack of long-term monitoring and scientific justification of choice of the monitoring points; insufficiency of on-line test of water properties. The aim of this study is to find spatial and temporal variation patterns in bog water hydrochemistry and to assess its impact on bog water catchments under conditions of various anthropogenic loading. Natural bogs in many ways condition the hydrochemistry of other surface water bodies within the catchment areas of bogs: rivers, lakes and streams. Specific indicators of bog water were analyzed afield. It is found as a result that water flow from bogs and from peatland, in particular, feature a high instability of characteristics: color, dissolved oxygen, oxygen saturation, electrical conductivity, acidity. The composition of cations and anions was determined on a laboratory scale. As a result of long-term monitoring from 2000 to 2022, the bog water color dependence on rain capacity, as well as the close correlation between the color and acidity of bog water with its electrical conductivity is revealed. As a case-study of the Tudovka river of the National Central Forest Reserve, it is found that in these natural conditions, the influence of bog water on the water receiver extends to 36 km. The obtained data are included in the electronic data base on hydrochemical and hydrophysical characteristics of bog water, including the type and degree of development of a peatland.
