u u F property was surveyed for evidence which is indicative of surface and/or subsurface on:No transformers are on the subject property. If a nearby transformer that contains e biphenyls (PCBs)were to leak or explode, it would be the responsibility of the owner to mitigate environmental contamination. No evidence of solid waste disposal was noted and the site was carefully inspected for environmental concerns originating form discolored, disturbed/subsided soils, stressed vegetation or unusual/noxious odors. None of these environmental indicators were present. No hazardous materials are stored on-site and there were no indication or observations of spills, drums or other items associated with hazardous materials. An important concern associated with the environmental assessment of agricultural properties is the issue of buried pesticide containers or discarded items. It was an occasional practice to dispose of containers by this method many years ago. To detect these types of underground artifacts is difficult even with the use of ground penetrating radar or other types of non-intrusive, subsurface analyses. The land surface did not exhibit visual indicators for buried containers such as surfacing of product residue, soil mounding or soil depressions, particularly in the Remainder area that is currently planted in pasture. Since the groundwater is very high in this locale, it is highly unlikely burial of containers took place. It is usually only after a contaminant plume has affected a domestic well that pesticide containers are discovered. The groundwater table is found approximately 8 feet under the property. This is considered a very shallow groundwater elevation. Shallow, or a high groundwater table can be impacted easier from pesticides or nitrogen as nitrate. The groundwater directional flow appears to be directly toward the north and then continues northeast as depicted on the attached Lines of Equal Elevation Map, published by the County Flood Control Department in 1992. As illustrated on the attached USDA Soil map, the predominate soil type over the property is Willows clay (#274). This soil type would be conducive to greater biological activity which would promote the degradation of organic molecules such as insecticides and herbicides. Additionally, a finer soil type such as a clay soil can promote denitrification and attenuate the downward migration of nitrate. Since the subject property has been in agricultural production for several years, an evaluation of environmental fate data for agrichemical residues as a nonpoint source of potential contamination was done. The science of pesticide residues in soil, air, surface water and groundwater is extremely complex and variable. Environmental models which attempt to predict pesticide behavior and transport in the environment are beyond the scope of this investigation. It has been clearly evident over the last five decades that the risk/benefit ratio regarding pesticides has been overwhelming benefit and comparatively low risk to the United States population and the environment, as a whole.
