ABSTRACT:
Freeze wells may be used to isolate an area for soil remediation. Freeze wells may form a frozen barrier around a treatment area. The frozen barrier may inhibit fluid from entering into the treatment area. The frozen barrier may also inhibit migration of contamination out of the treatment area. The frozen barrier may be used to surround all of the perimeter of the treatment area. A frozen barrier may also be formed above or below a treatment area. Freeze wells may be activated in advance of soil remediation so that a frozen barrier is formed when soil remediation is begun. The soil remediation may be accomplished by any type of soil remediation system, including a thermal soil remediation system. Heaters of a thermal soil remediation system may be may be placed close to the frozen barrier without the barrier being broken through during remediation.
