SCORE 56 101 N St Nw, Washington, Dc 20001 The purpose of this work plan is to describe the method and procedures for the abandonment of nine of the monitoring wells located at the dunbar high school. The monitoring wells must be abandoned to allow the construction of the athletic track and field to continue. The monitoring wells will be abandoned by making an attempted to remove the 2-inch pvc from the ground. If the pvc cannot be removed, a tool will be inserted into the well to rip the pvc to ensure that the well casing and screen are filled with the grout material. After the pvc has either been removed or ripped, powdered bentonite slurry with a 60: mix ratio of 1 lbs bentanite powder 94lbs cement and 82 gallons of water will then be placed using a tremie pipe from the bottom of the well/boring to the surface. Any waste material generated will be disposed of appropriately ![]() ![]() Client: District Of Columbia Department Of General Service | Permit type: Miscellaneous | Permit status: Permit issued | Permit id: Sb1400308 |
