Details and results of the percolation test are summarized in the following table. <br /> Table 2.

Satisfactor�r perc. <br /> rate <br /> Shallow Test <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. <br /> 1 Per San Joaquin County Environmental Health Department, a rate between 5.0 and 30.0 min/in requires an <br /> eight-foot separation between the bottom of dispersal system and ground water, or mitigation by system <br /> design or enhancement. <br /> Discussion of Percolation Test Results <br /> The soils near the proposed sewage disposal areas 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. <br /> Because of the percolation rate between 5.0 and 30.0 min/in encountered in the test <br /> hole, the San Joaquin County Environmental Health Department will require an eight- <br /> foot separation from the bottom of the dispersal system to ground water. Ground water <br /> is anticipated to be encountered approximately 68 to 90 feet below ground surface at <br /> the Site; consequently, no modifications to standard septic systems should be required. <br /> Discussion of Septic System Sizing <br /> Septic system construction should follow the San Joaquin County On-Site Wastewater <br /> Treatment Systems Standards (2017) where applicable. <br /> LOGE 20-44 Page 6 <br />
