Method and apparatus for in-situ chemical oxidation for soil and groundwater remediation

摘要

A method for treating groundwater and soil with a chemical oxidant, such as potassium permanganate, is provided. A chemical is placed in a powdered or pellet form into injection wells. Baffles are inserted into the ground to direct groundwater flow toward the injection wells. The groundwater flows through the injection wells to pick up the chemical oxidant. A second set of baffles are placed between the injection wells and the contaminated zone to disperse the chemical oxidant laden water. The chemical oxidant laden water flows through the contaminated field, the oxidant acting on the contaminated soil and groundwater to treat same. The injection wells can be pressurized to increase groundwater flow. Tests can be conducted on the other side of the contaminated field to measure the effectiveness of the treatment.
