I n Soil Profile And Percolation Tests Sheet 3 of 4 Existing U-se. (Cont ' d)_ There is a mobile home situate on a high Knoll in the south corner of the 40 acre parcel . It is furnished but apparently not being lived in at the present time . This is- the area where a home is planned to be bui.lt in the future and ,the area where the soil profile and percolation- tests ,'were performed . There is smaller mobile home beinglived in at the lower elevation land on the north end of the property . Water is being supplied to this . smaller mobile home by a booster pump bringing water from the Fetzer ' s family well located northerly of ' the property . A well is to be drilled on the lower elevation land north and west of the percolation testing area to supply water to the planned future home . Soil Profile Test : Excavation to a depth of 10 feet was performed for the soil profile test on Parcel No . 2 at the location shown on the attached Parcel Map . No water was encountered in excavating to the 10-foot depth . The soil immediately below the surface of the ground to a depth of about two (2) feet is a graish-brown clay material . From two ( 2) feet below the ground surface to a depth of ten ( 10 ) feet , the soil is a reddish-browm , course , sandy clay . Percolation Tests : Three percolation tests were performed . All were on Parcel No . 2 . They were performed in accordance with the percolation test procedures outlined in the "Xanual of Septic Tank Practice" , published by Department of Health , Education and Welfare and requirements of the San Joaquin County Public health Service , Environmental Health Department . Only one percolation test hole is required and that is Percolation Test Hole Vo . 2 . Percolation Test Hole No . 1 was dug to the standard 3-foot depth but is a larger diameter hole and intended only as research for studying the reliability and accuracy of applying a correction factor in the determination of the percolation rate for a larger diameter hole . Percolation Test Bole No . 3 is also a larger diameter hole and was excavated to a 10-foot depth and is intended only as research for studying the reliability and i accurracy of applying a correction factor in the determination of the percolation rate for a larger i diameter hole and also for comparison with the standard 3-foot depth test .
