Although DDT was banned in 1972, its presence in San Joaquin Valley soils is an indication of its long half-life. It is extremely unlikely there are any concentrations of DDT or its degradates in the property soils from farming operations that may have taken place on the property many decades ago. Any minute residual pesticide concentrations are inconsequential. § 3.3 Description of all current on-site potential and/or known above ground and below ground sources of contamination identified at the project site are included in Section 3.2. No sources of current aboveground contamination were observed, other than the referenced non -hazardous items described in Section 5 of this report. § 3.4 Description of all past off-site potential and/or known above and below ground sources of contamination identified in the area of the project site that could impact the site include: Information conveyed by the ERS documents indicate no listings, with no likelihood of impact to the property from a distant contaminated site. The GeoTracker document illustrates one listing within 1,000 ft radius from the property, and this site has the "completed - case closed" designation. Agricultural spray drift affecting the property from the nearest agricultural production land is an extremely slight possibility, since agricultural production occurs 1.5 miles to the east. § 3.5 Descriptions of all current off-site potential and/or known above and below ground sources of contamination identified in the area of the project site include those referenced in Sections 3.2, 3.3, and 3.4 above. Any contaminated sites can be considered "past" off- site sources of contamination that are simultaneously "current" contaminated sources. § 4.0 EVALUATION OF PAST AND CURRENT SOURCES OF CONTAMINATION IDENTIFIED AT OR NEAR THE SITE AND RECOMMENDATIONS FOR FURTHER ACTION § 4.1 Evaluation of each potential and/or known source of contamination identified in the Sections above have been discussed in the respective Sections to facilitate the transfer of information to the reader. § 5.0 CONCLUSIONS AND RECOMMENDATIONS § 5.1 The subject property contains garbage/trash, as noted in the photographic plates. This includes all types of discards; however, none appeared to be hazardous. No other types of hazardous materials were observed, nor was there soil staining or stressed vegetation that may be indicators of hazardous materials. Chesney Consulting
