However, we feel they are an accurate <br />representation of the true groundwater conditions on most of the sites due to the high permeability <br />of the native sandy soils. However, in area A, the organic soils (OL, PT) and fine clayey sands <br />(SC, SC-SM) likely did not allow the water to infiltrate into the holes. The water levels in that site <br />are likely to match the level of the adjacent wetlands along the street. <br />It should be noted that fluctuations in the level of the groundwater can occur due to variations in <br />rainfall, temperature, spring thaw and other factors not evident at the time of our investigation. <br />Mottled soils were observed. Mottled native soils are a historical indication of a temporarily or <br />seasonally saturated soil condition. Grey soils were also observed. Grey native soils are an <br />indication of a permanently saturated soil condition. <br />Laboratory Testing <br />Moisture Content Tests- Moisture content tests were performed on every split spoon sample in <br />accordance with ASTM method D2216; Standard Test Method for Laboratory Determination of <br />Water (Moisture) Content of Soil and Rock by Mass. Individual test results are shown on the <br />boring logs adjacent to the sample that was tested. <br />Organic Content Tests- Organic content tests were performed on selected split spoon samples in <br />accordance with ASTM method D2974; Standard Test Method for Moisture, Ash and Organic <br />matter of Peat and Other Organic of Soils. Individual test results are shown on the boring logs <br />adjacent to the sample that was tested. <br />Page 6 <br />
