Bio-polymer slurry trench method for installation of in-situ air sparging system
- Geo-Con, Inc., Mulberry, FL (United States)
An investigation was conducted at a site in Greenville Country, 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. The two trenches were installed using a biodegradable slurry in lieu of the bentonite slurry commonly utilized in the more traditional slurry trench technique. The slurry temporarily supported the trench walls while the air sparging components were submerged and set at the proper elevations Once backfilled with stone, the slurry in both trenches was broken by introducing a breaker solution which reduced the slurry to sugar water. The trenching, air sparging piping installation, and backfilling operations were completed in about six weeks.
