The present invention relates generally to systems and processes for ex-situ reformulation of contaminated soil to reduce contaminant concentrations below target criteria. An ex-situ reformation system for reducing the concentration of contaminants contained in a material includes a user interface and a decision engine configured to receive a plurality of input parameters from the user interface relating to each of two or more different material stockpiles available for reformulation. The decision engine is configured to determine a quantity of each stockpile for reducing an amount of processing required to perform the reformulation.
