No ground water was encountered in the boring. <br /> Generally,' soil mixtures of sand, silt, and clay were encountered in the boring.

One percolation test(percolation test hole no. 1) was set to a <br /> depth of 3 feet in a soil.consisting of a brown silty, fine sand. A second percolation test was set <br /> d <br /> to a epth of 8 feet in the brown fine to medium sand with"cla (percolation: test hole. Y (p o e no. 2). <br /> These two percolation test locations were separated by about 5 feet of distance. <br />�7 <br /> roots � <br /> r— z <br /> e ti <br /> - r <br />
