The effect of acid mine water on ground water hydro-chemical, in Mantewe, Tanah Bumbu Regency, South Kalimantan, Indonesia

Openly coal mining can damage the layer structure so that the groundwater aquifers that are in the aquifer layer filling out the coal mining pond. Free oxygen available at the mine accelerate the process of formation of acid mine water as the negative impact of mining coal. When the rainy season rain fell increase the amount of water that is mixed with coal at the mine pond, so the acid mine drainage can melimpas form the surface flow. The research location is in the district. Mantewe Kab. Land of Spices. At this location there are several coal mining sites openly. The purpose of this study was to determine the impact of acid mine drainage on water quality in the vicinity of the study. Test parameters on this research activity is determined only a few chemical elements that exist in South Kalimantan Governor Decree No. 05 of 2007 on the standard allotment and river water quality standard. Parameters-The parameters are: DHL, TDS, pH, Fe and Mn. From the data analysis lab, coal mining in the District Mantewe a negative impact in the form of acid mine drainage. Acid mine water accumulating in an ex-mine coal with a concentration parameters-the selected parameters exceed the quality standard limits allowed. Acid mine water flowing on the surface does not pollute the river that flows near the site of research and acid mine water that infiltrated into the soil into groundwater will not pollute wells-wells closest to the sites.
