' 2 <br /> Sand was added to the boring until the bottom was raised to approximately 17 feet bgs, <br /> followed by the installation of the SVE well The screened section (0 02-inch) for the SVE <br /> ' wells extends from 17 feet bgs to 10 feet bgs Sand was placed in the annular space surround- <br /> ing the screened section of the SVE well to approximately 9 feet bgs A 1-foot bentonite seal <br /> ' was placed above the SVE sand pack, followed by a slurry of neat cement grout in the annular <br /> space surrounding the well above the bentonite seal,extending to near the ground surface. <br /> The wellheads were then connected to a subsurface piping network Each SVE well <br /> has an individual line connected to the treatment area. Sparging wells are connected into two <br /> ' networks with valves and flow-measuring ports in each well Each double-completion well <br /> was then sealed in a traffic-rated wellbox. <br /> Project No. RC0309 010 <br /> GERAGHTY&MQLLER, INC �� <br />
