Abstract
Coal mining industry is an important sector in the regional economic of Indonesia. Many mining companies are widespread in Indonesia, especially in Kalimantan Island. It is recognized that environmental impacts of open pit mines are not only natural landscape changing, but also human health hazards. The most significant of them is the probability of groundwater contamination. According to environmental regulations in Indonesia, each mining company is obliged to have Environmental Impact Assessment (EIA) document, before starting production. The purpose of this study is to assess groundwater contamination hazard cause by mining activities, as a part of EIA. Groundwater contamination hazard is evaluated by combining the intrinsic groundwater vulnerability and the contaminants loading in the mine area. DRASTIC method is applied to obtain the groundwater vulnerability, while contaminant loadinng potential is evaluated based on stepwise procedure application. The results of this study are groundwater contamination hazard maps. Based on the hazard of contaminants, it can be concluded that the highest groundwater hazard area will be occurred at the North of study area. Therefore, the mitigation for the document of EIA will be concerned there. Furthere research may need to complete this preliminary study. Keyword: EIA, Loading Contaminant, Groundwater Vulnerability, Open Pit Coal Mine, DRASTIC
