1. A method for decreasing the amount of contaminant at a site in a subsurface, wherein at least a portion of the contaminant is extractable, comprising:

  • introducing an oxidant prior to or simultaneously with a surfactant into the subsurface;

    extracting extractable contaminant from the subsurface;

    characterizing the amount and/or distribution of contaminant in the subsurface;

    coordinating the extracting of contaminant and the introducing of oxidant and surfactant to reduce contaminant to a target amount.
