June 8, 2006 <br /> NOA Pro)ect Number: E06036A <br /> 6.6 Percolation Test Forms and Results <br /> The completed percolation test forms are included in the appendix of this report. <br /> .. A shallow percolation test is defined by the EHD as being between 36 and 42 inches in depth; a <br /> satisfactory percolation rate for a shallow test is less than or equal to 60 minutes per inch drop. A <br /> deep percolation test is defined by the EHD as being between 36 inches and 25 feet in depth; a <br /> satisfactory percolation rate for a deep test is less than or equal to 30 minutes per inch drop. One <br /> percolation test must demonstrate a satisfactory percolation rate within the proposed septic system <br /> disposal field of each parcel to utilize a standard septic system. Details of the percolation tests are <br /> summarized in Table 5. <br /> Table 5. <br /> Summary of Percolation Tests. <br /> Test No., Percolation Percolation Rate Test Comment <br /> Date Tested Test Depth(ft) (minutes/inch) Duration (see notes) <br /> Parcel 1-A(shallow) 3.20 5.0 4 hr Satisfactory percolation rate <br /> May 15,2006 <br /> Parcel 1-A (deep) 25.02 No movement 4 hr Failing percolation rate <br /> May 15,2006 <br /> Parcel 1-B(shallow) 3.15 No movement 4 hr Failing percolation rate <br /> May 15,2006 <br /> Parcel 1-B(deep) 27.23 No movement 4 hr Failing percolation rate <br /> May 15,2006 <br /> '— Parcel 2-A(shallow) 3.39 50.0 4 hr Satisfactory percolation rate <br /> May 15,2006 <br /> Parcel 2-A(deep) 14.78 No movement 4 hr Failing percolation rate <br /> May 15,2006 <br /> Parcel 2-13 (shallow) 3.46 250 4 hr Failing percolation rate <br /> May 15,2006 <br /> Parcel 2-13 (deep) 7.82 125 4 hr Failing percolation rate <br /> Maa 15,2006 <br /> Note: A satisfactory percolation rate for a"shallow"test is less than or equal to 60 minutes per inch. <br /> A satisfactory percolation rate for a"deep"test is less than or equal to 30 minutes per inch. <br /> 6.7 Discussion of Percolation Test Results <br /> The soils within the proposed septic disposal areas of the primary dwelling units of each parcel have <br /> demonstrated a satisfactory percolation rate for a standard septic system. <br /> The soils within the proposed septic disposal areas for the secondary dwelling units did not <br /> 8 <br />
