Four monitoring wells will be installed along the perimeter of the excavation. Each of the wells will be completed at a depth of 15 feet below ground surface from the surface grade. Therefore, a geoprobe direct push drill rig will be sufficient to install the monitoring wells. The three wells located along the permieter of the excavation will be installed using a geoprobe direct-push drill rig. The geoprobe uses a hydraulic hammer to push a macrocore lined steel rod with a polyethylene sleeve into the ground in four-foot increments. The macrocore is then withdrawn from the ground and the sleeve removed containing a relatively undisturbed soil core. The sleeve is cut open allowing examination and sampling of soil from the core sample. The purpose of this investigation is to characterize groundwater only, therefore soil samples will not be submitted for laboratory analysis. The wells will be completed as two-inch diameter pvc wells, with five feet of 0. 020-inch machine slot screen and pv
