A remedial composition comprising a soluble silicate, a surfactant, a polyol and water is disclosed. The remedial composition of the present invention is generally intended for use in the treatment of soil, sand, water, fly ash and other mediums that may contain hazardous materials. In one embodiment of the present invention the soluble silicate of the remedial composition has a mole ratio of about 2.6 to about 3.9 moles silicate per mole of alkali metal oxide. In another embodiment of the present invention the remedial composition will have a pH level ranging from about 10.5 to about 11.9. In another embodiment the water component further comprises from about 0.5% to about 15% dissolved oxygen (O2). In another embodiment of the present invention the remedial composition may be further diluted by adding water to create various solutions comprising about 1 to 300 parts water to 1 part remedial composition.
