CONCLUSIONS AND RECOMMENDATIONS <br /> From visual observations, there is no surface contamination. The probability of subsurface <br /> contamination from pesticides or other contaminants can be considered nonexistent-to-low, <br /> considering pesticide environmental fate data, the indigenous soil type and the depth to <br /> groundwater. Therefore, at this point in time, it is our opinion that no corrective action is <br /> required within the boundaries of the subject property. <br /> Potential groundwater contamination from the referenced pipeline and oil tanks, would in all <br /> probability, not affect the subject property. It can be reasonably assumed that the groundwater <br /> travels to the northeast, which would place these structures downgradient from the subject site. <br /> We do not recommend the well water be tested for a multi-residue pesticide screen consisting of <br /> analysis for Dinitroanaline, Triazine, Organochlorine and Organophosphates. This is primarily <br /> due to the fact the groundwater is deep, and that a comparatively small amount of land <br /> upgradient from the subject property has been intensely farmed. We recommend that bottled <br /> water should be used for drinking and cooking in homes with domestic wells. <br /> The subject property is outside of a delineated area in which all new wells must have a grout seal <br /> to 200 feet. <br /> It is our opinion that contamination originating from the existing septic tank is highly unlikely. <br /> Contamination is usually dependent upon the age and type of tank construction material. The <br /> next time the tank is pumped out, the sewage contractor can check the integrity of the tank. The <br /> density of septic systems in the surrounding area can also be considered very low. The density of <br /> systems is one of the prime factors for contamination of the underlying groundwater. <br /> Asbestos containing materials (ACM) testing from any portion of the existing buildings is <br /> outside the scope of this investigation. If the existing buildings are ever demolished, testing for <br /> ACMs should be done at that time. <br /> 4 <br /> Na!!ey Ag research <br />
