April 6, 2009 <br /> Environmental- Engineering- Geology Project Number 2009007 <br /> Discussion of Soil Lithology <br /> The sandy loam soils encountered indicates that the material maybe suitable for aseptic system. (� <br /> However, a percolation test is an approved method for determining the type of system that May <br /> be required for the site. <br /> 6. PERCOLATION TEST INFORMATION <br /> Site Map Showing Test Locations <br /> A site map is attached, see Plate A8. <br /> Number of Percolation Tests <br /> A total of =percolation1es where conducted. The forth borehole contained water at 21 feet <br /> (total borehole depth was 25 feet). No test was conducted in this borehole. <br /> Borehole Preparation and Presoak <br /> The soil boreholes were advanced on the site with a Drill rig on March 12, 2009. <br /> A 2-inch diameter FVC pipe with perforations on the bottom was used to measure the drop of <br /> water in the percolation test boring. Approximately 2 inches of"small gravel" were placed in the <br /> bottom of the open soil borehole, then the PVC pipe was installed on top of the gravel. <br /> Presaturation of the percolation test holes occurred 24 hours before each percolation test. l <br /> The depth of water used to pre-soak was 12 inches above the bottom of the borehole. <br /> Condition of the test holes after pre-soak <br /> After the 24 hour pre-soak, the two boreholes on the proposed parcel 2 appeared dry and intact 61 y) <br /> JR SQUARED CONSULTING,INC.
