Abstract
A method and system are described for removing contaminants from the phreatic zone, also known as the saturation zone, or groundwater. A barrier wall is constructed below the ground surface and in the path of flow of a contaminated groundwater plume. A well is constructed in advance of the barrier wall and is connected to the barrier wall via a pipe. Various remediation media may be lowered into the well to perform remediation on the contaminated groundwater before it passes through the barrier wall.
