Zhodnocení kvality podzemní vody v okolí haldy hutního odvalu a určení základních dlouhodobých trendů – případová studie Bohumín

Abstract

This thesis deals with the source of inorganic contamination from the site of the old metallurgical slag heap and its spread in rocks of Quaternary fluvial sediments. Assessed site constitutes anthropogenically affected area of metallurgical slag heap, which is part of a large industrial area and includes Landfill site of municipal solid and industrial waste. Another important factor is the presence of former dosing tank mine water afflux "unaffected" profile. To the possible effect of metallurgical slag heap itself and enters many other aspects that affect the final nature of the groundwater of the area. The primary long-term and seasonal trends of controlled substances in the groundwater - chlorides, sulfates, ammonium and fluoride - were evaluated based on the results of long-term monitoring of groundwater quality at the site, specifically for the period from 2005 to 2015 were also used results from earlier geological and hydrogeological surveys and last but not least important, knowledge of the physical-geographical conditions of the area. Migration of certain substances, were graphically interpreted as a model of groundwater flow model, including changes in concentrations of the substances in the groundwater using the program SURFER. Marginally was also evaluated the influence of atmospheric precipitation amount.
