Abstract
Based on the assessment of the ecological state of the geological environment of the Shatsk Lake District, which was carried out as a result of geological additional study of areas on a scale of 1:200,000 and preparation for publication of the State Geological Map-200 set of the territory of sheets M-34-VI (Vladava), M-35-I (Kamin-Kashirsky) [2], which were carried out by the Rivne Geological Party of the State Enterprise “Ukrainian Geological Company” in close cooperation with scientists from the National University of Water Management and Environmental Management, a database of geological and ecological data was investigated and created and the features of the structure of the geological environment of the Shatsk Lake District were studied; an assessment of technogenic impacts, including industrial emissions, accumulation of stable and radioactive elements, toxic compounds, development of mineral deposits on the geological environment was carried out; an assessment of the permissible technogenic load on the geological environment was carried out; a differential assessment of the ecological state of the components of the geological environment of the studied territory (pollution soils of geochemical landscapes, bottomsediments, surface and groundwater, impact by hazardous geological processes and phenomena); an integrated assessment was carried out according to the levels of tension of the ecological state of the geological environment. Priority was given to groundwater, soils and bottom sediments, since they are a source of toxicants entering the food chains directly. In particular, natural, anthropogenic, technogenic, residential, industrial, mining, water management, and transport landscapes werestudied. Technogenic and recreational load included the study of mainly agricultural and recreational areas. Assessment of contamination of the territory of the Shatsk Lake District, surface and groundwater determined the satisfactory ecological state of the geological environment (ESGS).Assessment of geochemical (hydrogeochemical) contamination of groundwater, assessment of contamination of soils and bottom sediments, total impact of the territory by hazardous EGP and phenomena allowed for an integrated assessment of the ESGS.
