"This research was conducted to assess the effectiveness of various disposal strategies in the abatement of pollution from mining solid waste. Column studies were undertaken to evaluate the quality and quantity of leachate generated by the disposal of a pyrite mine waste under various soil amelioration and layering configurations and to assess the vegetative uptake of potentially hazardous materials from the solid waste. Columns containing the mine waste under 0.3 to 1.2 meters (1 to 4 feet) of cover soil were used to assess the capability of the cover material to reduce leachate volume, improve leachate quality, and enhance the growth of cover vegetation. Concurrently, columns containing neutralizing materials were used to determine if such materials aided in retarding acid formation and pollutant migration throughout the soil. The results of this study illustrate that the quality of leachate resulting from the disposal of pyrite mine waste may be dramatically improved by incorporating lime, sewage sludge, and fertilizer into the upper strata of the mine waste; layering sewage sludge and fertilizer on top of the lime-treated mine waste; or by covering the mine waste with a relatively thick layer of cover soil. The study was conducted by the Industrial Environmental Research Laboratory of the U.S. Environmental Protection Agency (U.S. EPA) in the greenhouse of the U.S. EPA Test and Evaluation Facility (T&E Facility) in Cincinnati, Ohio from August 1980 through January 1981. It should be noted that the results obtained from these column studies reflect the experimental conditions under which they were obtained and may or may not be indicative of what would occur at an actual mine site during the same period of time."--P.
