Surface &Subsurface Contamination Report Page 14 Sandhu Farms Project No. 655.1 August 15, 2012 The Property was identified as the site of an exploratory natural gas well drilled by Mobil Oil E&P. The well was abandoned as a dry hole. No other listings identified the Property. No adjacent parcels were identified in the EDR database report except for three other exploratory gas wells nearby to the north. All were abandoned as dry holes. Diaz Farms at 27057 and 27041 Bird Road produced and disposed of hazardous waste in 2002. The facility also operated a small underground gasoline tank. Sasaki Farms at 27706 Bird Road also operated an underground gasoline tank that was closed. The US Army Tracy Defense Depot is about a mile west of Bird Road. This facility is identified in a number of databases, most significantly in the NPL database. This listing is the National Priority List, meaning that the site is on the federal list of EPA "Superfund" cleanup sites. The facility is engaged in producing, treating, and disposing of hazardous and acutely hazardous wastes. The wastes include petroleum products, solvents, pesticides and hazardous heavy metals. Since 1942, all of these materials have impacted the soil, primarily through unlined treatment ponds and pits. Most of the material has been confined to the soil, however chlorinated solvents have affected the groundwater. No other sites within a mile of the Property were identified. Based on the results of the EDR report, it was not deemed necessary to further investigate off-site facilities except the Tracy Defense Depot. 3.2 State Records Regarding Tracy Defense Depot Based on information obtained from the State's Envirostor website htti)://www.envirostor.dtsc.ca.gov/, the contaminated soil above the saturated zone has been adequately mitigated. Based on information obtained from the State's GeoTracker website htti):Hp,eotracker.swrcb.ca.gov/, the groundwater remains impacted by solvents, primarily perchlorethane (PCE). A recent summary from March of 2012 of groundwater conditions prepared by the State Regional Water Quality Control Board (attached in Appendix E) indicated that the contaminants have migrated north easterly with the direction of groundwater flow, but have not approached the subject Property. 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc.
