The Percolation tests conducted on October 20, 2021 and November 19, 2021 yielded a <br />percolation rate between 5.0 and 30 min/in. At this rate, a minimum 8 feet of soil separation is <br />required between bottom of the dispersal field and the groundwater. The SSNL reports a historic <br />groundwater level of 110 to 123 feet below surface grade. (San Joaquin County OWTS Standard <br />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 Trainee, at <br />fgarciaruiz@sjgov.org or (209) 616-3032. <br />Steven Shih, REHS <br />Program Coordinator <br />c: LiveOak <br />1868 E.
