Percolation Test Results <br /> The completed percolation test form is included in Appendix 3 of this report. The form <br /> was signed by Mr. Escotto and indicates the percolation rate for each hole based on the (o <br /> final water drop observed. <br /> Per San Joaquin County Environmental Health Department's definition, a shallow <br /> percolation test hole has a depth between 36 and 42 inches; a satisfactory percolation <br /> 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 /> 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 3.40 <5.0 4 hr. Satisfactory <br /> 11/18/14 perc. rate <br /> Shallow Test <br /> P2 3.30 <4.4 4 hr. Satisfactory <br /> 11/18/14 perc. rate <br /> Shallow Test <br /> Note: A satisfactory percolation rate for a"shallow"test is less than or equal to 60 minutes per inch.A satisfactory <br /> percolation rate for a"deep"test is less than or equal to 30 minutes per inch. <br /> Discussion of Percolation Test Results <br /> The soils within the percolation test areas have demonstrated satisfactory percolation <br /> rates for the use of standard septic systems in accordance with the requirements of the (� <br /> San Joaquin County Environmental Health Department. <br /> Discussion of Septic System Sizing <br /> Septic system construction should follow the San Joaquin County On-Site Wastewater <br /> Disposal Standards (2003) where applicable. According to Muniappa Naidu, Lead <br /> Senior Registered Environmental Health Specialist at the San Joaquin County <br /> Environmental Health Department, the Site is located in an area where septic <br /> contractors sometimes encounter difficulty with seepage pits due to sandy soil <br /> conditions; the type of system to be used should be selected in consultation with the <br /> septic contractor (personal communication, December 11, 2014). <br /> LOGE 1422 Page 7 <br />
