In summary, <br /> volatile organic compounds (VOCs), including trans-1,2-dichloroethylene, <br /> trichloroethylene, and carbon tetrachloride from facility operations have impacted <br /> groundwater. Groundwater extraction and treatment remediation was initiated in <br /> 1987 and 1990 to control groundwater migration. Based on Kleinfelder's review of <br /> pproximately 2,676 the most recent groun <br /> Depot, San Joaquin 700 East Roth Road south SWRCB GeoTracker dwater maps obtained from documents available on the <br /> Defense Distribution Aonline database, groundwater beneath this facility flows <br /> Sharpe Site toward the northwest. Contaminated groundwater plumes associated with this <br /> facility appear to extend to the northwest (URS, 2012 and 2016), and not northerly <br /> toward the subject Site. Based on the cross-gradient location of this facility from <br /> the Site with respect to the direction of groundwater flow, it is unlikely that this <br /> facility affected soil, soil vapor or groundwater beneath the Site. Thus, it is not <br /> considered a REC. <br /> This facility was listed as maintaining ASTs with a total capacity of 47,450 gallons, <br /> and ten underground storage tanks (USTs) reported as closed. This facility was <br /> Granite Construction Co 10500 South Harlan Approximately 906 feet also listed as having a closed leaking underground storage tank (LUST) case <br /> south-southwest involving groundwater that had been impacted by gasoline. Based on information <br /> obtained from the SWRCB GeoTracker TM database for this facility (see Section <br /> 4.3.6), the release associated with the LUST case is not considered a REC. <br /> 20172543.001A/ST016R49461 Page 19 of 54 November 2, 2016 <br /> ©2016 Kleinfelder ww Aeinfelder.com <br />
