Impact of Coal Refuse Disposal on Groundwater

摘要

The objective of this study was to determine the extent of groundwater quality deterioration when coal mine refuse and power plant ashes were disposed of in open pits. In addition, disposal methods were developed and procedures for planning and designing disposal sites were formulated. The study was conducted from 1975 to 1979 at an abandoned sand pit near Boguszowice, Poland, where the groundwater was monitored. Laboratory testing of the wastes and its leachates were also conducted. From this work, the physical-chemical character of the waste material and its susceptibility to leaching of particular ions in the water environment were determined, as was the influence of precipitation on the migration of pollutants to the aquifer.
