ABSTRACT:
A soil treatment process is provided utilizing a polymer enhanced foam to block the flow of a migratory fluid in a soil. Placement of the polymer enhanced foam in a desired treatment region of the soil produces a seal that substantially eliminates the permeability of the treatment region to the migratory fluid and prevents migration of fluid across the region. In each of its numerous embodiments, the process can be employed as either a remedial or a preventative treatment.
