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.
Claims10
A groundwater remediation system, comprising:
- a barrier wall constructed in the path of flow of a contaminated groundwater plume;
- a first well constructed between the barrier wall and the groundwater plume, said well having a permeable lower portion and removable remediation media;
- a pathway connecting said permeable lower portion of said well to said barrier wall, said pathway passing through said barrier wall in a manner such that the contaminated groundwater first passes through the permeable lower portion containing the remediation media, the pathway, and then the barrier wall.
A method for the remediation of a contaminated groundwater plume, said method comprising the steps of:
- constructing a barrier wall in the path of flow of said groundwater plume;
- constructing a first well between the barrier wall and the groundwater plume, said first well including a permeable lower portion adapted to receive remediation media;
- providing a pathway through said barrier wall to said permeable lower portion of said first well, thereby defining a gate;
- and
- lowering a remediation media into said first well down to said gate.
A groundwater remediation system, comprising:
- a barrier wall constructed in the path of flow of a contaminated groundwater plume;
- a first well constructed between the barrier wall and the groundwater plume, said well having a permeable lower portion;
- a pipe connecting said permeable lower portion of said well to said barrier wall, said pipe passing through said barrier wall in a manner such that the contaminated groundwater first passes through the permeable lower portion, the pipe, and then the barrier wall;
- a removable remediation media located in the permeable lower portion of the well, at the location of the pipe, to act as a gate through which the contaminated groundwater must pass;
- and
- a second well constructed after the barrier wall.
