| Short description: |
ISF involves injecting or infiltrating an
aqueous solution into a zone of
contaminated soil or ground water, followed
by extraction and above ground treatment of
the elutriate (the flushing solution mixed with
contaminants). In some rare cases, the flushing solution and treated contaminants may be left in place. The solutions used for ISF may consist of surfactants, cosolvents, acids, bases, oxidants, chelants, solvents, or water. Recent applications have also documented the use of cyclodextrin, a non-toxic, modified sugar, as a flushing agent. These flushing solutions typically increase the mobility or solubility (or both) of the contaminants. Many organic and inorganic contaminants can be treated using ISF, including NAPLs, VOCs, SVOCs, PCBs, pesticides, non-volatile metals, cyanides, and radioactive contaminants.
