necessary to define the lateral extent of impacted soil However, because groundwater depth <br /> at the site is approximately 12 to 15 feet, it is conceivable that the impacted soil call be <br /> removed by excavation Upon removal, the excavated soil can be transported and disposed <br /> at a properly licensed landfill <br /> 5.2 Hydrocat bon Impacted Groundwater <br /> Groundwater grab samples collected during the drilling of soil borings indicate two plumes <br /> (one gasoline, one diesel) of impacted groundwater It appeals tliat gi oundwater 1s impacted <br /> in the area of the USTs and near the northwest portion of the property Hydrocarbons were <br /> not detected in samples collected from borings near the eastern and southern portions of <br /> the property. Additional samples will be requited to assess the lateral extent of impacted <br /> groundwater at the site <br /> 5.3 Removal and Replacement of USTs and Dispensers <br /> It appeals that the oil-site USTs and dispenser islands aie the sources of hydrocarbons in <br /> soil and groundwater at the site Therefore, we recommend removal and/or replacement <br /> of the present USTs and dispensing systems After removal, impacted soil can be excavated <br /> and treated or disposed Monitoring wells call then be installed to assess the lateral extent <br /> of impacted groundwater <br /> 6.0 LIMITATIONS <br /> Our professional services were performed using that degree of care and skill ordinarily <br /> exercised by envrr onnnental consultants practicing in this or similar localities The findings <br /> were based upon analytical results provided by an independent labotatoiy Evaluations of <br /> the geologic/lnydrogeologrc conditions at the site for the purpose of this investigation ate <br /> made from a limited number of available data points (n e monitomig wells, soil samples) <br /> and subsurface conditions may vary away fron3 these data points No other wartarnty, <br /> expressed or implied, is made as to the professional recommendations contained in this <br /> report <br /> A.du Sarvae+.I..
