The Fall 1998 and Spring 1999 maps are the most current maps available from the county. Examination of these maps indicates that no water level data is available for the Tracy/Banta area, which includes the Site,and no definite comments as to depth or gradient flow direction can be ` made. However, our office estimates that, at its shallowest, the ground water in the area lies 10 to 15 feet below the ground surface. ` No ground water was encountered by the staff of Neil O.Anderson&Associates, Inc. during the drilling of the percolation test holes to a depth of three to three and a half feet on February 24, 2005 and March 8, 2005. 4
