An investigation was conducted at a site in Greenville County, South Carolina which detected contaminants in the groundwater. It was then decided that remedial action was required. The contaminants and their location in the groundwater led to the selection of an in-situ air sparging system to be installed at approximately thirty-four feet deep. Due to design depth requirements and other site conditions, the bio-polymer slurry trench (B-P drain) Method was utilized in the air sparging system installation
