There is also a large tank near the western apex of Parcel 1 that has the entire top cut off and has been placed downward. On-site, conventional septic systems with tanks and leachfield areas serve the residential and mobile home structures. As noted on the attached Soil Survey map, the subject property is composed of only one soil type: Hollenbeck silty clay(#173). Effluent percolation is expected to be slower in this silty clay soil. An intermittent hardpan stratum also exists. It is unknown at this time if there will be any improvements made to Parcel 2. The farming and dairy operations were conducted by Mr. Van Vuren. Since the dairy was, and still is completely organic, there have been no agrichemical applications for the past six years. Any p q) nearby agrichemical mixing and application must be done very carefully so that the Van Vuren property is not impacted. This is particularly applicable for the recently planted almond orchard \ directly north of Parcel 2. Therefore, assurance is made that material applied nearby has been done 3 S/ correctly and accurately to its intended target without drift. The subject property was surveyed for evidence which is indicative of surface and/or subsurface contamination: There are four transformers on Parcel 1 that exhibited no evidence of oil leakage. If the transformers were to leak or explode, it would be the responsibility of the transformer owner to mitigate environmental contamination. Evidence of typical solid waste storage and disposal on Parcel 1 included used farm equipment, containers, metal,would,plastic, and other nonhazardous materials and objects. Obviously, no commercial hazardous material agrichemicals are stored on-site. The site was inspected for environmental concerns originating from discolored, disturbed/subsided soils, stressed vegetation or unusual/noxious odors. None of these environmental indicators were observed on Parcels 1 or 2. However as referenced, Parcel 2 acreage is currently in pasture and somewhat difficult to observe. 4t An important concern associated with the environmental assessment of agricultural properties is the issue of buried pesticide containers or discarded items. It was an occasional practice to dispose of containers 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. It is usually only after a contaminant plume has impacted a domestic well that buried pesticide containers are usually discovered. Due to the underlying hardpan layer and tight, �) compact soils, it is unlikely this practice occurred in this locale. The static groundwater table is found approximately 103 feet under the property as illustrated on the attached Lines of Equal Depth to Groundwater Map published by the Flood Control District. This is considered a deep groundwater elevation. Impact from nitrate to comparatively deep groundwater is usually not as significant as with shallow groundwater. This is particularly true if there are intervening layers of clay down to the static water table, thereby attenuating adverse constituents. The soil profile to the depth of groundwater consists of heavier soils of clay and silt. The referenced hardpan layer can also have an attenuating effect on the downward migration of nitrates. Groundwater directional flow appears to be toward the northwest toward a zone of recharge, as denoted on the attached Lines of Equal Elevation Groundwater map. Although the subject property has been in agricultural production for five decades, there was no y� evaluation of environmental fate data for agrichemical residues as a nonpoint source of potential contamination since none have been applied for at least the past six years. 3 Chesney Consulting
