(Ground Zero) on your behalf for the above-referenced site. In the work <br /> plan, Ground Zero proposes to sound the three onsite .monitoring wells to total depth to <br /> ensure there are no obstructions present. Then the well traffic boxes will be removed and the ' <br /> wells will be destroyed by over drilling the boreholes to total depth (using eight-inch or <br /> larger augers). The boreholes will be backfilled to surface grade with neat cement grout <br /> using a tremie pipe system. <br /> EHD approves the work plan as submitted and will issue the well permit application for <br /> destruction of monitoring wells MW1, MW2, and MW3 within the week.
