§ 3.3 Description of all current on-site potential and/or known above ground and below gro7in sources of contamination identified at the project site would include the items discussSections 3.1 and 3.2. These items occurred in the past and now can be considered curren on-site potential and/or known above ground and below ground sources of contamination identified at the project site. In addition, there are currently no electrical transformers on the property. Environmental fate data shows that the half lives of present-day agrichemicals are comparatively short and moderately persistent within the soil environment. These materials pose a minor risk to human health and the environment. § 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 has or may impact the project site have been referenced above in Section 3.1 and 3.2. In addition, nitrate contamination of the underlying groundwater may be a potential source of contamination due to the immense amount of agricultural production in this region. As referenced, the likelihood of DBCP contamination is a possibility. Soil data and information will also be provided in the Soil Suitability Study. Agricultural spray drift(non-target) from surrounding production land may contribute to above ground contamination of the subject property, although for relatively brief periods of time. Long- term persistent agrichemicals, namely DDT is probably found in the on-site soils, since it is found in virtually all San Joaquin Valley soils. Residual DDT that may be present within the on-site soils poses an insignificant risk to human health, or to the environment. §3.5 Description of all current off-site potential and/or known above and below ground sources of contamination identified in the area of the project site have also been referenced in Section 3.1 and 3.2. Future use of the project site will be rural residential, with the application of agrichemicals on surrounding properties. Protection of these new residential structures from ground-applied, or air-applied application of agrichemicals will be accomplished by spraying in the early morning hours when there is typically no wind. § 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 above Sections have been discussed in the respective Sections to facilitate the transfer of information to the reader. Discussion of environmental concerns are also found in the following Conclusions Section. Chesney Consulting
