1.0 INTRODUCTION <br /> Under contract to Chevron Pipe Line Company(CPL), Radian International LLC <br /> (Radian) completed a limited groundwater investigation as described in the Work Plan for <br /> Groundwater Sampling at 35275 Welty Road, Vernalis, California (Radian, 1997). Vernalis is <br /> located in southern San foaquln County (Figure 1-1). <br /> The purpose of the investigation was to determine if groundwater has been <br /> impacted by trichloroethene(TCE) from historic steel can manufacturing operations at 35275 <br /> I <br /> Welty Road (site). CPL will use the results contained in this report to facilitate a decision <br /> [ whether or not to accept environmental responsibility for TCE at the site. Available analytical <br /> data indicate that petroleum hydrocarbons are present in the soil and groundwater at this site. In <br /> addition, TCE associated with non-CPL activities has been identified in soil at the same locations <br /> where petroleum hydrocarbons are present. TCE was not detected in groundwater during <br /> previous investigations; however, during previous investigations the detection limit for TCE was <br /> elevated because of sample dilution. <br /> i 4 <br /> 35275 Wclty Road,Vcmalis 2 March 1997 <br /> 11 11 <br /> I I <br />
