July 31, 2023 <br /> BGG No. G130.09D <br /> no water remained in the hole. As such, percolation testing was then performed by pouring <br /> approximately 6-inches of water into the test hole and measuring the drop in the water level over a <br /> single 30-minute interval. Some water remained in the hole at the end of the initial 30-minute <br /> interval;hence percolation testing continued by pouring approximately 6-inches of water into the test <br /> hole and measuring the drop in the water level at 30-minute intervals for a total period of four hours, <br /> refilling with water as needed. The results of the percolation test are contained in Appendix A. <br /> Percolation Test Results <br /> A rate of 10.0 minutes/inch was recorded for the proposed septic system and leach field. SJCEHD <br /> defines a shallow percolation test hole as having a depth between 36 and 42 inches; a satisfactory <br /> percolation rate for a shallow test is one resulting in a water level drop greater than or equal to 1 <br /> minute per inch(min/in)but less than or equal to 60 min/in. For the site to utilize a standard septic <br /> system, one percolation test must demonstrate a satisfactory percolation rate within the proposed <br /> septic system disposal field. <br /> Discussion of Percolation Test Results <br /> The soils within the proposed septic system leach field area have demonstrated a satisfactory <br /> percolation rate for the use of a standard septic system in accordance with the requirements of the <br /> SJC EHD. <br /> Discussion of Septic System Sizing <br /> Septic system construction utilizing leach lines should follow the San Joaquin County On-Site <br /> Wastewater Treatment Systems Standards (2017) where applicable. <br /> BAEZ GEOTECHNICAL GROUP Soil Suitability Study&Nitrate Loading Study-Becerra Residence,18163 S.Carrolton Road Page 5 <br />
