V. GROUND WATER DEPTH AND TESTING Currently there is a well on Parcel 2 serving the Frisk residence with the capability of providing all the water necessary to irrigate the pastures on the existing 6.2 acre parcel. Mr. Frisks well is to a depth of approximately 250 feet with excellent water quality. V1. SOIL PROFILE AND PERCOLATION TESTS Three test holes for percolation were drilled to a depth of 36" each and 12" in diameter. Visual classification of each soil stratum encountered was made in the field by a Civil Engineer at the time the test holes were drilled_ The location of the test holes are shown on the attached application. The deep pits are recommended to be to a depth of 25' . Percolation tests were performed in the holes with a copy of these tests attached. It can be seen frau the tests that the perk rate for the tests ranged fran 25" to 29" per hour on the deep holes whereas they in most cases did not meet the 1" minimum per hour on the shallow holes during the first testing. We feel that the deep holes more then meet the requirements as set forth by the State and San Joaquin County Public Health Services Division. We reca[mend the Septic tanks, leach lines with deep pits as laid out in the County leach line requirements based on number of bedroans. V11. CONCLUSION Based on the results of the percolation test, the soil profile and the past performance of the existing septic systams in the area and the wells in service in this area would not be adversely affected or be detrimental to the ground water supply and will meet the requirements of the San Joaquin County Public Health Services Department. V111. LIMITATIONS The conclusions in this report are for the information gathered only and does not warrent any portion of the site not tested. It is assumed that the test results should be representative of the site as a whole. Sincerely, William Armstrong, P.E.
