n <br /> Surface &Subsurface Contamination Report Page 4 <br /> Sandhu Project <br /> Project No. 597.1 <br /> February 12, 2009 <br /> • Agricultural pesticides and other chemicals have been periodically applied <br /> to the crops on the Property. This application appears to be in accordance <br /> with accepted practices, but chemical use in past years cannot be entirely <br /> documented. We understand the Property is intended to remain in <br /> primarily agricultural use, but any planned new home sites could <br /> potentially expose residents to elevated concentrations of residual <br /> pesticides. <br /> No current or past use of aboveground or underground fuel tanks was <br /> identified, although there is very limited information concerning the prior <br /> building complex that predated 1963. The area of the former building <br /> complex has since been plowed and ripped, and cultivated for many years. <br /> The is no remaining visible trace of the site. <br /> Given the recent construction of the existing building complex, it is <br /> likely to include asbestos in construction materials, and there appears <br /> Jtt <br /> little potential for a hazardous release to have occurred. <br /> (Property <br /> f the Property as agricultural land appear unlikely to have impacted <br /> cognized environmental condition, except as otherwise listed above. <br /> ossibility that the former farm building complex that existed prior to <br /> 1963 may have included the use and storage of agricultural chemicals and <br /> petroleum products. <br /> En vironmental Conditions Impacting Site from Off Site Properties <br /> Based on the results of the EDR State and Federal environmental database <br /> search, and on the site reconnaissance, it does not appear likely that any off-site <br /> facilities have impacted the Property with a recognized environmental condition. <br /> ecommendations <br /> We have performed a Surface and Subsurface Contamination study of the <br /> roperty at 26206 sson Road (APN 239-230-03, & -04), Tracy, California in <br /> co 0 aSan Joaquin County Development Title 9-905, Section 12. <br /> Based on the conclusions set forth above Geo-Phase Environmental, Inc. <br /> recommends the following additional work to investigate or mitigate <br /> environmental conditions associated with this Property: <br /> 1. Any future home sites should be subject to soil testing to determine if <br /> there are hazardous concentra ions—ofpossible residual chlorinated �- <br /> pesticides. We suggest that a four-pointcomposite sample should be <br /> adequate for each home site. —sem ple should--be su cte-d—to <br /> 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc.
