The subject property was carefully inspected for environmental concerns originating from discolored, disturbed/subsided soils, stressed vegetation or unusual/noxious odors, particularly from drug manufacturing operations. None of these environmental indicators were present. The land surface did not exhibit visual indicators for buried containers such as surfacing of product residue, soil mounding, or soil depressions. It was obvious that since virtually the entire property is in agricultural production, the trees would most likely show severe stress if there was shallow subsurface contamination. It is usually only after a contaminant plume has impacted a domestic well that buried pesticide containers are discovered. If buried items are discovered during any future earthwork procedures, etc.,the San Joaquin County Environmental Health Department must be contacted immediately. § 3.41 § 3.5 It is a possibility minute volumes of agrichemicals sprayed on surrounding properties may drift onto the subject property, in addition to the agrichemicals applied to the subject acreage. The site can be considered in the predominant downgradient windshed to other agricultural production acreage. In addition, the San Joaquin County Mosquito Abatement District may spray for mosquitoes on and around the property. The herbicides Roundup (Glyphosate) and Surflan (Oryzalin)have been applied to the acreage for weeds. Environmental Fate Data for the materials applied to the peaches as documented on the Environmental Questionnaire is found in Appendix D. Environmental Fate Data is summarized in the chart found in the next section. The data shows that the materials are moderately persistent and have comparatively short half-lives within the soil environment. As referenced, mixing of these materials with water occurs off-site because a custom applicator applies these materials to the farmable acreage. An important concern associated with the environmental assessment of open properties is the issue of buried containers or discarded items. It was an occasional practice to dispose of containers or discarded items 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. From previous Nitrate Loading and Soil Suitability Studies done around of the property, it is known there are high concentrations of nitrate in the underlying water table and drinking water aquifers. This can be attributed to the intensely farm eg . Static groundwater is found approx ely 55 feet unde the property as illustrated on the attached 1999 Lines of Equal Depth to Grou water map. Fr the 2003 Lines of Equal Elevation of Groundwater, the groundnter der do pears to be to the north-northeast. A groundwater depth of 55 feet can be considered a medium depth groundwater elevation. This may attenuate i_ ct from serious point source releases, and agrichemicals such as pesticides and herbicides. The degree of impact from adverse constituents can be mitigated when there are intervening layers of clay soil down to the water table depth. However, alysis c nducted for the Soil Suitability Study for this project reveals a nitrate concentrion of 58 ppm n' ate for the on-site domestic well. The Maximum Contaminant Level (MCL) 3 in drinking water is 45 ppm. This high concentration can unquestionably be attributed to the intense agricultural production in this area for the past six decades. Page-4- Chesney Consulting
