West-northwest, or <br /> upgradient wind shed is composed mostly of agricultural production land including rice fields, <br /> pasture, dairies and row crops. This wind direction, along with the fact that agrichemicals cannot / <br /> be applied during windy conditions, ensure that the likelihood of impact to the property from <br /> unintended pesticide drift is somewhat unlikely. <br /> 4. EVALUATION OF PAST AND CURRENT SOURCES OF <br /> CONTAMINATION IDENTIFIED AT OR NEAR THE SITE AND <br /> RECOMMENDATIONS FOR FURTHER ACTION <br /> § 4.1. The following site specific information was obtained from direct observations and an <br /> interview with Mrs. Sorrenti on November 21, 2006. A final inspection of the property was <br /> conducted on November 16, 2006. There are no wells on the pr� ty. Irrigation water is supplied <br /> as ditch surface water from Oakdale Irrigation District(O.I.D.).(No ardous materials were noted <br /> on the property. No evidence of drug manufacturing or the dumpaof drug-related chemicals was <br /> observed on any of the roads or levees surrounding the property acreage. Dumping of eighttires was <br /> noted at the pavement edge of Steinegul Road and the property. It is recommended that these tires be <br /> removed. Adjacent to the south of the subject property is the former San Joaquin County <br /> Mosquito Abatement and defunct landing strip facility. Operations of the District ceased in <br /> approximately 1994. Potential contamination is unknown. No electrical transformer exists on the <br /> property; therefore there should be no threat from polychloride biphenyls (PCBs). <br /> 5 <br /> Chesney Consulting <br />
