摘要

The purpose of this research is to characterize residual solids from hydraulic fracturing in the Marcellus Shale to predict leaching behavior in the natural environment for elements of concern. Solid samples were subjected to strong acid digestions to determine the total environmentally available concentration of elements and to weak acid digestions with various extraction fluids (reagent water, inorganic acid, organic acid, and synthetic municipal landfill leachate) to determine worst-case leaching potential in various disposal environments. Comparing these results, it is possible to determine the effect of extraction fluid and sample characteristics on the leaching potential of select elements. This may be further developed to determine best management practices for the disposal of hydraulic fracturing residual solids.
