Two borings and four tests were made in the primary <br />treatment area, and one boring and two percolation tests <br />were made in the alternate (future) location. All the boring <br />and test locations are shown on the attached sketch. <br />SOIL CONDITIONS <br />The attached copies of the field boring logs show that the <br />soil profile is fairly similar throughout. About ,' of dark <br />brown topsoil overlies sandy clay (CL), which classifies as <br />a clay loam according to the USDA Soil Textural Classification <br />System. The clayey soil changes in color from a fairly uniform <br />brown to a brown mottled as depth increases. The mottled brown <br />is not the typical multi -colored, mottled soil, which indicates <br />a fluctuating ground water table. <br />GROUND WATER <br />No water was noted in the borings at completion, although the <br />soil was nearly saturated, which is typical of late spring <br />conditions. Later, water was noted at depths of about 5' in borings <br />1 and 2. This may have been due to the heavy rains the pre- <br />vious day and evening; or, it may be due to the tempor:-y <br />spring conditions. <br />OFFICERS. <br />CHARLES W.
