1. A method for remediating a hydrocarbon-contaminated region of a subterranean body of groundwater to destroy or reduce the initial concentration levels of hydrocarbon contaminants, comprising the steps of:

  • (a) providing a plurality of mutually spaced wells intersecting said groundwater region;

    (b) determining the existence of acceptable continuity and well interflow paths for the said region by generating a test flow of a solution of hydrogen peroxide from one of said wells and monitoring pH changes at each other of said wells as a function of time to detect a pH drop of at least 0.2; and

    (c) subsequent to detecting said pH drop, providing a treating flow of said hydrogen peroxide solution from one or more of said wells.
