Joe Cange Subsurface Investigation for Suitability Of On-Site Sewage Disposal, Lots 3, 6, 8, 10, 13, 22, 24, 25, 28, and 31/32; Tract B, Spring Forest Subdivision (Forsythe Property) Dear Mr. Cange: Test Holes were drilled on the subject lots to determine sub- soil conditions and to determine suitability for on-site sewage disposal. Transmitted herein are the soil logs for the test holes with accompanying laboratory testing, and results of per- colation tests run in these holes. Also attached is a test hole location sketch. The locations shown are approximate. They were located using topographic features and by pacing distances. We recommend strongly that they be located by sur- vey as soon as possible to avoid confusion later. The test holes were drilled on April 21 and 22, 1981, using a Nodwell mounted, Mobile B-50 drill fitted with a solid flight auger. The drill rig is owned and operated by Denali Drilling, Inc. The drilling was supervised and the test holes were logged by Mr. O.H. Hatch, geologist with Alaska Testlab. Grab samples were obtained at five foot intervals in each test hole, were visually' identified, and were sealed in plastic bags to preserve the natural moisture content. After drilling, a per- forated, 3/4 inch PVC pipe was placed in each test hole to monitor water table elevations and to run the percolation test.' The percolation tests were performed by filling the test holes with water and allowing them to saturate. The following day, the holes were refilled with water, and the elevations of water in the holes were measurd at 10 minute intervals for a one hour period. The percolation rate given in this report was computed using the rainimum 20 minute absorption recorded i.n the percola- tion test. The following table lists the measured percolation rates. Joe Cange May 20, 1981 Page 2 Lot Test Hole Recommended Design Percolation Rate 3 I 10.0 6 4 7.3 8 5 10.0 10 6 7.6 13 7 16.0 22 8 10.0 24 3 10.0 25 2 4.2 28 '.. 10 (High Ground Water) 31/32 9 ' 3.2 The measured percolation rates in ~est Holes 1, 3, 5, and 8 were actually less than 10.0 minutes/inch; however, we recom- mend using this more conservative value due to the silty nature of ~he soil. A perc test was not run in Test Hole 10, because the high water (less than one foot) makes this area unsuitable for on-site sewage disposal. Disposal systems should be placed between 5 and 12 feet below the surface except for Lots 31 and 32 where the systems should be kept as shallow as possible to maintain'the necessary separ- ation from the seasonal high ground water level. If you have any questions regarding these tests, please feel free to call. Very truly yours, ALASKA TESTLAB Carl h. Bassler Geotechnical Engineer CAI]/mg At tachmc~]ts Approved by: Melvin R.
