The surface soil consisted of a brown silty sand that changed to a slightly silty sand with increased depth. <br /> The surface soil was underlaid by a stratum of slightly to moderately cemented fine sand that continued to the <br /> maximum depth explored. No ground water was encountered in the test pit at the time it was excavated. <br /> A percolation test was performed 30 feet west of the test pit. An 8 inch diameter test hole was <br /> excavated to a depth of 36 inches. The test hole was filled with water 24 hours prior to running the test. The <br /> test data obtained is enclosed in the Appendix. The results of the test indicate that the soil had a percolation <br /> rate of 2.9 minutes per inch. <br /> For approximate location of both the test pit and percolation test please see the Parcel Map in the <br /> Appendix. <br /> VII CONCLUSION <br /> Based on the results of the percolation test,the soil profile,and the history of surrounding septic systems <br /> in the area, it is our opinion that the subject property is well suited for the construction of typical septic tank <br /> and leach line sewage disposal system. However, the system should be designed and constructed under the <br /> guidelines established by the San Joaquin County Department Environmental Health. <br /> Based on the depth to ground water in the area and the soil profile encountered in our test pit, it is our <br /> opinion that the installation of the proposed septic system, if properly installed, should not adversely affect the <br /> quality of the ground water in the area. <br /> VIII LIMITATIONS <br /> The conclusions of this report are based on the information provided regarding the existing and <br /> proposed land use and development and on the site conditions as they existed at the time we excavated our test <br /> pit and performed the percolation test. It was assumed that the test pit and percolation test results are <br /> representative of the subsurface conditions in the general area. <br /> Our professional services were performed, our findings obtained, and our conclusions proposed in <br /> accordance with generally accepted engineering principles and practices.
