ABSTRACT:
The invention involves the selective emplacement of an impermeable polymeric barrier in the semi-permeable substructure, faulted or fractured geologic barriers which underlie leaking waste disposal sites. The emplacement of the barrier requires the creation of a horizontal fracture below the waste disposal site and the injection of a gellable solution containing a synthetic or biologically produced polymer into the fracture. The solution is then allowed or caused to gel in situ within the subterranean formation.
A proppant may be dispersed in the gellable solution. The proppant may be a waste active material.
