' No substantiating evidence of residual soil contamination was found during the current phase of <br /> investigation Any residual hydrocarbons that may exist should be precluded from affecting <br /> groundwater by the low leaching potential of the host soil and by the effective transport barrier <br /> present above groundwater The host soil is amenable to supporting natural biodegradation <br />' Residual soil contamination, if any exists, does not pose a threat to groundwater quality <br /> RECOMMENDATIONS <br /> Based upon chemical and biophysical analytical results of soil samples collected beneath the site, <br /> we conclude that natural biodegradative process have successfully reduced residual hydrocarbons <br />' in soil to levels which are currently below laboratory detection limits Should residual <br /> hydrocarbons in soil exist, it poses no threat to groundwater quality Further, analytical results <br /> of groundwater samples collected beneath the site confirm that groundwater has not been <br />' impacted Therefore, we recommend the site be considered for case closure <br /> Please call William Hunter at (916) 972-7941 or Greg Stahl at (209) 952-3481 if you have any <br />' questions regarding the project <br />' Sincerely, <br /> WM J HUNTER & ASSOCIATES <br />' BY <br /> ill VJ Hunter <br /> Pro ct Manager <br />' r�RED GE <br /> GROUND ZERO ANALYSIS, INC �(O <br /> 4 GREGORY P. <br /> STAHL <br />' BY No. 5023 <br /> Gregory P ttahl <br /> CA Registered Geologist No 5023 �rF OF CALF <br /> Ipc Ms Elizabeth Thayer, CRWQCB <br /> Mr Dudley McGee, Ham mertown Properties <br /> Mr Pete Voskes, Normac Inc <br /> groundzelnormaclsumrepor 95 8 <br />
