July 6, 2004 NOA Project Number: E04017A Page 3 Soil Properties and Percolation Tests Two (2)percolation test holes and six (6) soil borings were located on and nearby the 2' Fairway(see sheet G2). The test holes and borings were drilled with either a 6-inch diameter tractor mounted auger operated by the SG&CC or a 4-inch hand auger drilling tool operated by Neil O. Anderson& Associates, Inc. The soil.boring locations and other points between were measured with a laser level to roughly determine the topographic features of the disposal field (Plate 1). The surface soils encountered within the sewage disposal area were found to be a brown silty fine to medium sand or clean fine to medium sand which appears to be fill soil. The fill soils overlay a native grayish brown to black organic silty clay(see Plate 1). Table 1. Soil Description.

The soils in this area were thought to represent the soil underlying the sandy fill soil of the 2nd Fairway. For each percolation test hole, approximately 2 inches of pea gravel were placed in the bottom of the boring. A 2-inch diameter open ended and slotted PVC pipe was place on the bottom and backfilled with about 0.5 foot of pea gravel in the annular space. The holes were then saturated 24 hours prior to the percolation test. The holes were filled with water to 6-inches above the gravel and the water drop was measured each 112 hour for a period of 4 hours.
