• Details and results of the percolation tests are summarized in the following table. <br /> Table 2. Percolation Test Summary <br /> Test No., Percolation Percolation Test Duration Comments <br /> Date Tested Test Rate (see notes) <br /> Depth (ft.) (minutes/inch) <br /> P1 3.35 6.25 4 hr. Satisfactory <br /> 8/31/2016 perc. rate <br /> Note:A satisfactory percolation rate for a "shallow"test is less than or equal to 60 minutes per inch. <br /> Discussion of Percolation Test Results <br /> The soil within the percolation test location has demonstrated a satisfactory percolation <br /> rate for the use of a septic system in accordance with the requirements of the San <br /> Joaquin County Environmental Health Department. <br /> Discussion of Septic System Sizing <br /> Septic system construction utilizing leach lines, leach lines with sumps, or a filter bed <br /> should follow the San Joaquin County On-Site Wastewater Disposal Standards (2003) <br /> where applicable. The Site is located in a borderline area where San Joaquin County <br /> Environmental Health Department may also allow seepage pits to be installed. The <br /> Wastewater Disposal Standards indicate that, prior to installation of pits, the drilling of a <br /> test hole 35 feet in depth may be required to determine whether ground water is <br /> present. Based on the results of the nitrate loading analysis (to follow), however, the <br /> use of pits is not recommended. <br /> • LOGE 1623 Page 6 <br />
