Percolation test conducted on 21 January, 2022 yields percolation rate of 14.71 min/inch. At this rate <br />an 8' soil separation is required between bottom of dispersal field and the groundwater. Groundwater <br />is reported at 45 to 55 feet below grade. (San Joaquin County OWTS Standard Table 1.10.2). <br />c. Destroy the existing water well and construct a new water well that complies with the San Joaquin <br />County Well Standards under permit and inspection by the EHD as required by San Joaquin County <br />Development Title, Section 9-1115.5(e) & 9-1115.3. <br />d.
