CONCLUSIONS AND RECOMMENDATIONS Section (c) of San Joaquin County Development Title 9-905.12 states "Corrective Action: If the report indicates there are surface and subsurface contamination, corrective action shall be recommended in the report and concurred with by Environmental Health prior to the issuance of the building permit." The only environmental concerns observed on the subject property were the referenced household de minimus environmental items,which can be found at virtually every � residence, and is therefore, inconsequential. A final inspection of the property was conducted on July 19, 2004. Potential environmental impact from the listed sites suggests that there is no possibility of adverse impact to the subject property due to the distances involved. The closest referenced sites located in the Envisions Program Information at EHD and GeoTracker are crossgradient in relation to the subject property. Potential environmental impacts from past, present or future facilities within a one mile radius is unknown at this time, but highly unlikely. It is my professional opinion that since the property has not been farmed, potential impact from agrichemicals can be considered low-to-nonexistent, other than from DDT. Considering the environmental fate data for DDT and related compounds presented above, which would be the most likely persistent agrichemical, and most likely to have been used on the property prior to 1972,reveals any concentrations that may exist should be extremely low. The depth to groundwater of 100 feet would make impact from adverse constituents a very low probability in comparison to a shallow groundwater depth. The probability for nitrate contamination of the underlying aquifers originating from surrounding septic systems is extremely low due to the very low density of systems in the study area. However, nitrogen fertilization of surrounding cropland may contribute to a higher nitrate concentration in the underlying groundwater. Prospective buyers of proposed Parcel 2 must realize the subject property is surrounded by agricultural production land. Consequences of this surrounding land use include: pesticide/herbicide applications, noise, dust, odors, insects, machinery, crop dusting aircraft, trucks, exhaust and other !i� environmental effects that may be offensive to some people. It is recommended that these environmental effects be conveyed to any prospective purchasers, especially with regard to the County"Right-to-Farm" Ordinance. Page -5- Chesney Consulting
