Solid materials, such as soils, containing contaminants are treated with hydroxylradicals, in the gas phase. The hydroxyl radicals are created by hydrogen peroxide or ozone, preferably a combination of hydrogen peroxide, ozone and UV light. A de- contamination unit (10) for on-site use in the treatment of contaminated sol id materials, such as contaminated soil, is a totally en- closed closed-loop system containing a soil augers (16), a first UV light po rt (22), a hydrogen peroxide storage tank (24), further augers (34, 48), a second UV light port (38), peroxide spray nozzles (28, 42 ) and an air supply fan (50).
