Hand auger samples will be placed in laboratory supplied glass jars. <br /> Additional samples will be selected at intervals where visual signs of lampblack or other contamination are observed. <br /> 2 Depths are from original Site grade. Soil samples may be collected from deeper intervals based on field observations. Soil gas samples will only be collected <br /> from a depth of 5 feet bgs. <br /> 3 Grab groundwater sample to be collected from Boring E3-2 at approximately 9 feet bgs(assumed depth to groundwater). <br /> PARSONS Page 1 of 1 <br />
