From the bovine nutrient calculations, it is apparent that the Van Vuren Dairy has sufficient <br /> acreage to accept nutrients produced by the dairy animals. <br /> It is our opinion that contamination originating from the existing septic tank and leachfield on <br /> proposed Designated Remainder is unlikely since the groundwater is deep. Contamination from <br /> a septic system tank is usually dependent upon the depth to groundwater, soil type and density. <br /> The density of septic systems in the surrounding area can also be considered extremely low. <br /> Density is one of the prime factors for nitrate contamination of the underlying groundwater. If high <br /> nitrate concentrations exists in the underlying aquifers, it is most likely from agricultural inputs. <br /> Asbestos containing materials(ACMs)testing from any portion of the existing buildings is <br /> outside the scope of this investigation. If the existing residential structure or dairy barn is ever <br /> demolished or remodeled,testing for ACMs should be done at that time. <br /> LIMITATIONS <br /> The purpose of this report is only to inform the Client and the San Joaquin County <br /> Environmental Health Department of the environmental conditions as they currently exist at the <br /> subject site and within the parameters established in the County Ordinances.
