Abstract

The production of waste has caused environmental crises that have put the life of the planet in serious trouble; Waste disposal sites are important in this time. The purpose of this study is to investigate the ecological effects of waste disposal site of Nahavand city on semi karstic springs with an emphasis on hydro geochemistry by method of experimental-survey. In the first step, visit was made of the case study and sampling of the site was carried out, then document and collected water sample of chemical and microbial samples were provided to experts. Results of this study indicate that there is no relationship between concentrations of elements; only concentration of Hg Pb more increased due to proximity to landfill (200 m). Due to the fact that the rock bottom is a volcanic rock of the oven and limestone, and such stones have a significant non-resilient erosion and significant permeability, they have an inappropriate capacity for waste disposal, according to the meteorological data for the dominant wind of the study area, is the northwest and the west wind dominates, and as part of the city of Nahavand and the villages surrounding the suggested landfill area along the west. The area under study will not be safe from the effects of an unpleasant smell of landfill. The current burial ground is located almost on the natural drainage route, which makes the site ineligible for hydro geological purposes for landfill (The proposed site has not been justified in terms of environmental standards). Therefore, the suggested area has low capacity for waste disposal in terms of environmental permeability. The results of chemical and microbiological tests indicated spring pollution. So, it recommended that studies are carried out for the selection of suitable areas.
