Prospects for the elimination of toxic waste at the polygon of "Krasny Bor"

They’ve investigated the history and current state of the largest in the North-West region industrial toxic waste polygon "Krasny Bor", as well as possible ways to eliminate the accumulated environmental damage at the landfill. The design of the "Krasny Bor" testing ground was started in the 1960s, during the period of industrial growth, when the developing industry of Leningrad - metallurgy, heavy engineering, chemistry, petrochemicals, pulp and paper - began to produce more and more toxic waste, dumps of domestic waste was unsafe. More than 10 squares were surveyed in Lomonosov, Tosnensky, Volkhov and Vsevolozhsk districts of Leningrad region. The most suitable was the site located 6.5 km southeast of Leningrad border in Tosnensky district of Leningrad region near the village of Krasny Bor. The main advantage of this section was the presence of powerful deposits of blue Cambrian clays (up to 70 m deep) located close to the surface of the earth, possessing almost absolute waterproof properties (filtration coefficient 1,2х10-9 sm /s). The most rational way to eliminate the environmental damage accumulated at the site is a comprehensive method in which wastes contained in open maps are completely or partially processed by one of the above methods, and waste in sealed cards is isolated in a way that excludes their negative impact on the environment. In the event of any emergencies, for example, the burning of oil-containing wastes or the breakthrough of dams on the fence of open maps, atmospheric air will be contaminated with dangerous combustion products or pollutants enter the surface and underground water bodies of Leningrad Region, and through them into the Gulf of Finland and Baltic Sea. © IAEME Publication.
