A process for improved remediation of polynuclear aromatic hydrocarbon and/or polychlorinated hydrocarbon contaminated solid materials by integrated chemical/biological treatment comprising contacting the polynuclear aromatic hydrocarbon and/or polychlorinated hydrocarbon for chemical treatment with hydrogen peroxide in the presence of ferrous ion in liquid solution at a temperature of about 10°C to about 100°C, oxidizing the polynuclear aromatic hydrocarbon materials and/or polychlorinated hydrocarbon materials and producing more readily biodegradable hydrocarbon product materials, and then biodigesting the product materials by aerobic and/or anaerobic biodigestion. A lower alcohol added to the chemical treatment in accordance with one embodiment further enhances oxidation of 4- to 6-ring aromatic hydrocarbon contaminants.
