The Percolation tests conducted on June 15, 2022 yielded a percolation rate of 250 min/in and <br />1.81 min/inch. At this rate, a minimum 20 feet of soil separation is required between bottom of the <br />dispersal field and the groundwater. The SSNL reports a historic groundwater level of 160 feet <br />below surface grade. (San Joaquin County OWTS Standard Table 1.10.2). <br />b. The OWTS and its 100% replacement areas shall meet all required minimum setbacks stated in <br />San Joaquin County (OWTS) Standard and Well Standard. <br />If you have any questions please contact Francisco Garcia Ruiz, Environmental Health Specialist, at <br />fgarciaruiz@sjgov.org or (209) 616-3032. <br />r� /' - y <br />Fo <br />Steven Shih, REHS <br />Program Coordinator <br />1868 E.
