This was the first groundwater monitoring event to take <br /> place at the site. The test results show that detectable concentrations of the aromatic <br /> hydrocarbon compounds (BTEX) and total petroleum hydrocarbons (TPH-G) are present in <br /> one of three monitoring wells. The fuel oxygenate compound, MTBE was also present in this <br /> well (MW-1). <br /> LGroundwater gradient is 0.0025 ft/ft flowing N80°W. Depth to groundwater at the site was <br /> approximately 61.5 feet below ground surface (bgs). <br /> i p <br /> L <br /> 1.0 GROUNDWATER MONITORING <br /> 1.1 Hydrogeology of Site <br /> � The dominant soil type in the upper 75 feet of subsurface geologic soils investigated is sand, <br /> with fine to coarse-grained texture. Varying amounts of silt and silty sand were encountered <br /> from borehole to borehole. A couple laterally discontinuous clay lenses were encountered in a <br /> few of the boreholes. <br /> i <br />
