L <br /> LApril 13,2006 <br /> NOA Project Number: E05130B <br /> 6.6 Percolation Test Forms and Results <br /> The completed percolation test form is 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 as being between 3.5 and 25 feet in depth;a satisfactory percolation <br /> rate for a deep test is less than or equal to 30 minutes per inch drop. Either a shallow or deep <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 4. \ <br /> Table 4'. <br /> �. Summary of Percolation Tests. <br /> j.
