mss. <br /> ground water it was not possible to perform the test at this time. To perform the shallow <br /> percolation test a 36 inch deep by 8 inch diameter test hole was excavated by hand. Two <br /> inches of gravel:was placed in the bottom of the hole. A 3 inch diameter perforated pipe <br /> was then placed in the hole and backfilled with gravel. The test hole was filled with water' <br /> 24 hours prior to running the tests. The last half hour of the test readings were witnessed <br /> by:a county health official and the test data obtained is presented on Plate No. 6. The <br /> percolation rate has been adjusted to account for the gravel and pipe backfill. Calculations <br /> for adjustments are on the test data sheet.
