A method used for in situ remediation of contaminated subsurface ground and subsurface water using chemically or biologically reactive sheets. The reactive or active sheets contain one or more selected compounds capable of recovering, destroying, degrading and immobilizing contaminants in the soil or water. The compounds that will be selected depends on the contaminants to be treated. The compound may be diatomaceaous earth pellets or other porous materials inoculated with selected non-pathogenic microbes, a zero-valent metal such as iron, tin, aluminum and zinc, a leachable compound such as sodium percarbonate or an adsorptive compound such as activated carbon and zeolite. The contaminants may be petroleum hydrocarbons, chlorinated hydrocarbons and other hazardous chemicals. The sheets are formed by injecting a slurry of the selected compound into the subsurface using hydraulic fracturing where the orientation of the fractures is influenced by cutting and preparing a bore hole prior to the injection of the slurry. Also the sheets may be formed by employing high velocity jet-assisted fracturing using air, water and other fluids. The jet-assisted fracturing operates prior to or concurrently with an introduction of a slurry of the selected compound. The sheets may be formed horizontally, vertically and at angles dipping from the horizontal.
