Surface&Subsurface Contamination Report Page 3 Sandhu Farms Project No. 655.1 August 15, 2012 • A small poly tank of pesticide (glyphosate) also near the barn (8) does not appear to have impacted the underlying soil. Indoor Installations • Buildings on the site predate 1978 and therefore pose the theoretical potential to include asbestos-based construction materials. The homes on the Property were not entered, but the site reconnaissance did not reveal the presence of fibrous material likely to contain such materials. • Staining to the concrete floor from waste oil containers in a lean-to attached to the barn (1) is unlikely to have impacted the underlying soil. • Pesticides stored in the barn (8) are on a slab floor and therefore unlikely to impact the soil in the event of a release from a container. (See the maps in Appendix A for graphical representations.) Past Use of Proparty The past use of the Property has been entirely agricultural. Historical air photos (Appendix Q suggest the recent use of the Property was to grow orchard crops. The land was formerly used to grow row and grain crops since at least 1937, the date of the earliest air photo (see Appendix Q. The assessor's building records (Appendix F) suggest this general use extends back to at least 1900. The Assessor's building records do not suggest the past use of underground fuel tanks or other installation likely to pose a risk of a hazardous release. Environmental Conditions Impacting Site from Offsite Properties As a part of this investigation, EDR was contracted to perform a search of State and Federal electronic environmental databases for an area around the subject Property (see Section 3.1 and Appendix D). The Property was not identified in the EDR database report except as the site of a properly abandoned exploratory gas well dilled in 1974. The well was not productive and does not represent an environmental concern. No adjacent parcels were identified in the EDR database report except for three other exploratory gas wells nearby to the north. All were properly abandoned 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 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc. Phone: (209)569-0293 Modesto, CA 95356 Fax: (209)569-0295
