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. A plurality of mutually spaced wells are provided intersecting the groundwater region, and the existence of acceptable continuity and well interflow paths for the said region is determined by generating a test flow of a solution of hydrogen peroxide from one of the wells and monitoring pH changes at each other of the wells as a function of time to detect a pH drop of at least 0.2. Subsequent to detecting the pH drop, a treating flow of the hydrogen peroxide solution is provided from one or more of the wells. A system to enable the foregoing is also disclosed. |
