Laboratory analytics] results frot1f11 the water sammpee indicated <br /> concentrations of petroleum hydrocarbon constituents were not detected at or above the respective <br /> laboratory reporting limits, A copy of a portion of Kleinfelder's Phase I ESA report and the associated <br /> laboratory analytical report are included as Attachment 6. <br /> P <br /> K.razan Groundwater Sampling . <br /> As a precautionary measure, Krazan recommended that an additional groundwater water saimple be <br /> collected from well MW-1 and analyzed for petroleum hydrocarbons. on May$, 2000, Krazarn sounded <br /> the well, including measuring the depth of the well and the depth to groundwater. Based on the <br /> measurements,the total water volume of the well was calculated and three volumes were purged prior to <br /> sampling. A single water sample was then collected from the well and submitted, under COC,to SunStar � <br /> Laboratories, Inc_, of Tustin, California., for analysis of total petroleum hydrocarbons (TPI .as gasoline <br /> (TPH-G) and diesel(TPH-D); benzene, toulene, ethylbenzene, and total xylenes(BTEX); methyl tertiary i <br /> butyl ether (MTBE); and total lead in accordance with EPA, Methods 8015m, 8020, and 6010. These <br /> constituents were not detected at or above the respective laboratory reporting limits in the sample from <br /> MW-1. A copy of the laboratory analytical report, COC, and chromatogram for the aromatic volatile <br /> hydrocarbons are attached(Attachment 7). <br /> Couclusion <br /> Groundwater samples collected during the installation of well MW-1, installed in 1991 to monitor <br /> groundwater near the site's former VST, and the subsequent groundwater sampling in June 1996 and <br /> May 2000 indicate that petroleum hydrocarbon constituents, including NME, were not detected at or <br /> above the laboratory reporting limits. Thus, there appears to be no impact to groundwater from <br /> petroleum hydrocarbon near the former UST. These results and the information provided by this request <br /> are intended to satisfy the needs of the SJCEHD and support the granting of"no further action" status for <br /> E <br /> the subject site. <br /> KRAZAN&.A,SSOcIATES,INC. <br /> Offlees Serving the Western,United States <br /> 3400009.Itr <br /> J ;0 <br />
