COMPLETED PERCOLATION TEST FORM <br /> After completion of the test,the EHD inspector reviewed the field data and signed the required EHD <br /> Percolation Test Rate form. Field measurements recorded during the test are included on the <br /> Percolation Test Rate Field Sheet provided in Appendix C. <br /> j <br /> j <br /> 6.7. POTENTIAL PROBLEMS PREDICTED <br /> On site soils within the shallow percolation test range demonstrated adequate percolation.rates. <br /> Additionally, the existing west septic system has been properly operating. The proposed activation <br /> of the north septic system should be sufficient to provide for expected winery-associated operations. <br /> j <br /> 6.8. PERCOLATION TEST FINDINGS <br /> The shallow percolation test performed provided a satisfactory percolation test rate.The percolation <br /> rate of 8.4 minutes per inch was calculated from data collected during the 1-hour percolation test. <br /> Activation of the north septic system should follow the San Joaquin County On-site Wastewater <br /> Disposal Standards. <br /> r � <br /> 7.0 CHEMICAL AND PHYSICAL PROPERTIES OF SOIL <br /> Soil chemical properties were supplied by regionally sourced material for the surrounding area. } <br /> i <br /> 1 <br /> 7.1.
