Abstract
Compositions and methods of using such compositions for treating subsurface soil in an aquifer to remove contaminants that may be present in water of the aquifer. The composition includes a first solution and a second solution. The first solution includes at least one chemical capable of being effectively bound to soil to form a sorbent matrix by reacting in the subsurface. The second solution includes at least one chemical capable of reacting with at least one of the chemicals in the first solution in order to create the matrix. The first and second solutions are chosen so as to react on a time scale allowing at least one chemical in the first solution to bind to the soil.
