CrIn addition, it is highly unlikely there has been agrichemical drift which may have impacted the bject property. 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. CONCLUSIONS AND RECOMMENDATIONS From visual observations, there is no significant surface contamination. Environmental concerns that may pose problems such as used tires, empty drums and containers may be considered de minimus environmental concerns. Many of these de minimus items are related to the past farming and dairy operations conducted by Mr. Van Vuren. These items were, and are stored as replacements to existing equipment. Considering the confines of the Parcel 1, housekeeping becomes an issue since there appears to be a small area to store a large amount of material and replacement items. As photo-documented, there was a cart that contained several replacement batteries that was f3 3 located at the north side of Parcel 1. Mr. Van Vuren has subsequently removed these batteries and taken them to a recycle facility. The probability of subsurface contamination from pesticides can be considered low-to-nonexistent, considering the historical organic operation of the dairy and surrounding cropland which includes Parcel 2. The surface soil type (<5 ft) is predominately a silty clay/clayey silt. The biological 5 activity of this soil type would be expected to be higher than in sandy soils, thus creating a favorable environment for microbial decomposition of organic molecules. Previous well water testing done on the dairy well revealed a nitrate concentration of 9 ppm, as (5 1) nitrate. However, regardless of the well water chemical analyses, bottled water should always be used for drinking and cooking. The subject property is outside of delineated areas in which all new wells must have a grout seal to 200 feet. It is my opinion that contamination originating from the existing septic tanks and leachfields on Parcel 1 is unlikely since the groundwater is deep. Contamination from a septic system is usually dependent upon the depth to groundwater, soil type and system density. The density of septic systems in the surrounding area can also be considered extremely low. Density is one of the prime factors for nitrate contamination of the underlying groundwater. Asbestos containing materials (AGMs) testing from any portion of the existing buildings is outside the scope of this investigation. If the existing residential structure or related structures including the mobile home are ever demolished or remodeled, testing for ACMs should be done at that time. 4 Chesney Consulting
