III. SITE CONDITIONS <br /> 1. The Site itself is part of the dividing line between Henning Tract and <br /> McDonald Tract of McDonald Island. As stated above, the Site occupies an area that used <br /> to be part of Whiskey Slough. Over the years the surrounding soils have subsided (due <br /> to farming and natural conditions) leaving the old sloughbed higher than the surrounding <br /> land. Because of this past relation to the slough, the soil type of the Site is Fluvaquents. <br /> Typically this soil has a surface layer of silty clay loam with the underlying layers being <br /> sandy loam, silt loam and silty clay. [Attached hereto as Exhibit "C" is the United States <br /> Department of Agriculture, Soil Conservation Service - Holt Quadrangle Map and excerpts <br /> from the October, 1992, Soil Survey of San Joaquin County.] <br /> 2. The soil at the Site is also suspected of having deposits of soil from the <br /> neighboring land as the Site was a point at which 1982 flood waters flowed from Henning <br /> Tract to McDonald Tract. <br /> The neighboring soil on the easterly (McDonald Tract) side is Itano silty clay loam. <br /> Permeability of this soil is moderately slow. The neighboring soil on the westerly (Henning <br /> Tract) side is Rindge mucky silt loam. Permeability of this soil type is rapid. The <br /> Henning Tract soil is commonly known as "peat". This soil has many naturally occurring <br /> microbes. Tests have shown the soil to actually act as a purifier as the microbes therein <br /> consume contaminants. <br /> 3. The water table in the area is directly affected by the tidal pressures exerted <br /> by the neighboring Sacramento-San Joaquin Delta waterways. Subsurface water levels vary <br /> from approximately 4 to 25 feet below ground surface level. The Owner/Operator does not <br /> believe that the depth of materials at the Site reach below the neighboring ground surface <br /> level. <br /> 4. The Owner/Operator has no evidence that the materials at the Site have <br /> contaminated the groundwater. However, appropriate sampling and testing shall confirm <br /> 5 <br />
