79-429 <br />Rebers Construction <br />-3- August 9, 1979 <br />Results of the percolation tests indicate the area testes' will be <br />quite suitable for drainfield development. The results of the <br />two percolation tests average out to 12.5 minutes per inch (mpi) <br />which is well below the necessary 60 mpi rate required for drain - <br />field development. It should be noted, however, that these <br />results are unusually low for a clayey sand. The layers of sand <br />encountered in P-2 may be the reason for the low rates. Future <br />tests over a wider area may find higher rates. <br />GENERAL: <br />We appreciate this opportunity to be of service to you on this <br />project.
