ABSTRACT:
A method of remediating soil contaminated with inorganic and organic pollutants as disclosed. A method comprises treating the soil with a complexing agent capable of chelating the pollutants and a matrix-generating agent for authigenically generating within the soil an alumino-silicate colloid matrix. The matrix has a plurality of reactive sites, which are capable of physically and chemically altering the pollutants into innocuous forms. The matrix-generating material comprises a mixture of a cement, blast furnace slag, fly ash, organophilic clay, and a free radical generator.
