A 2-inch diameter PVC pipe <br /> with open ends and slots was placed in the hole. About 6-inches of pea gravel was placed in the <br /> annular space around the pipe. The hole was pre-soaked 24 hours prior to the test with 12 inches of <br /> water above the bottom of the hole. Presoaking of the percolation test hole occurred on May 31, <br /> 2005. <br /> I <br /> k Percolation tests were conducted for the borings on June 1, 2005 in accordance with the <br />
