Abstract
The results of the survey (spatial scanning) in the summer of 2021–2022 of the ecological and geochemical state of the waters of the Upper Volga from Lake Seliger to the Gorky Reservoir (city of Chkalovsk) and the long-term (since 2002) geochemical monitoring of the lake, river and ground waters of the Lake Seliger basin are discussed. They made it possible to reasonably identify two serious environmental problems for the water areas of the Volga River as a result of unregulated nature management. These are the eutrophication of waters near the cities of Myshkin and Yaroslavl. Here the phosphorus content in the water is 400- 500 mcg P/l. Sources of phosphorus are urban areas, settlements, recreation. This is confirmed by the high content of phosphorus in the groundwater of the coastal settlements of the Selizarovsky part of Lake Seliger. Similarity is for the spring waters of the Volga River valley between the cities of Tver and Dubna. Pollution of the Volga River near the city of Kostroma with industrial waste has been detected. The same is observed in the waters of the Sheksna River above the city of Cherepovets. Indicators of pollution are Fe, Ce, Nd. Solution of environmental problems: for cities and industries it is improvement of waste water treatment methods; for all natural-anthropogenic landscapes it is creation of forest barriers in the coastal part of rivers and reservoirs from incoming pollution.
Supporting agencies: The research was carried out within the framework of the state-ordered research theme of the Institute of Geography of RAS FMWS-2024-0007 “Biotic, geographical-hydrological and landscape environmental assessments to create the foundations of rational nature management.”
