rate for a shallow test is greater than or equal to 1 minute per inch (min/in) but less than <br /> or equal to 60 min/in drop. A deep percolation test hole has a depth between 3.5 and <br /> 25 feet; a satisfactory percolation rate for a deep test is greater than or equal to 1 min/in <br /> but less than or equal to 30 min/in drop. For the Site to utilize a standard septic system, <br /> one percolation test hole (shallow or deep) must demonstrate a satisfactory percolation <br /> rate within the proposed septic system disposal field. <br /> Details and results of the percolation testing are summarized in the following table. <br /> Table 2.

Satisfactory perc. <br /> Deep Test rate <br /> Note: A satisfactory percolation rate for a "shallow"test is greater than 1 but less than or equal to 60 minutes per <br /> inch. A satisfactory percolation rate for a "deep" test is greater than 1 but less than or equal to 30 minutes <br /> per inch. <br /> Discussion of Percolation Test Results <br /> The soils within the proposed sewage disposal area of the Site have demonstrated a <br /> satisfactory percolation rate for the use of a standard septic system in accordance with <br /> the requirements of the San Joaquin County Environmental Health Department. This <br /> percolation test is considered representative of soils within a 100-foot radius of the test <br /> location. <br /> Discussion of Septic System Sizing <br /> Septic system construction utilizing leach lines with seepage pits should follow the San <br /> Joaquin County On-Site Wastewater Treatment Systems Standards (2017) where <br /> applicable. <br /> LOGE 2104 Page 7 <br />
