rate for a shallow test is less than or equal to 60 minutes per inch (min/in) drop. A deep <br /> percolation test hole has a depth greater than 3.5 up to 25 feet; a satisfactory <br /> percolation rate for a deep test is 30 min/in or less. For the Site to utilize a standard <br /> septic system, one percolation test (either a shallow or deep test) must demonstrate a <br /> satisfactory percolation rate within the proposed septic system disposal field. <br /> Only shallow tests were performed for the Site. Details and results of the percolation <br /> tests are summarized in the following table. <br /> Table 2.
