F <br /> REPORT <br /> SUTTER HOME WINE PROCESSING FACILITY <br /> PERCOLATION TEST <br /> 1.0 INTRODUCTION <br /> Percolation tests were performed at the site in accordance with procedures traditionally used by the San <br /> Joaquin County Public Health Services Department of Environmental Health Division (EDH) to asses the <br /> efficacy of leach fields for sewage disposal. Mr. Steve Mindt of the EDH inspected the tests. <br /> Groundwater was observed within 26 inches of the surface. Percolation rates from all four tests were <br /> 4 equal to or greater than 480 minutes per inch. This report satisfies the scope of work described in the <br /> Consulting Agreement Change Order, dated August 26, 1998, between Southeast Facility Engineers, Inc. <br /> and Condor Earth Technologies, Inc.(Condor). <br /> .2.0 FIELD INVESTIGATION <br /> Four percolation test borings were installed on Monday, August 31, 1998 at the locations shown on the <br /> attached map. All test holes were 12 inches in diameter. Test holes were 36 inches deep at PERC 42, <br /> E PERC #3, and PERC #4. Groundwater was encountered at 26 inches below the surface in the first test <br /> hole, PERC #1. A substitute hole was drilled to 18 inches in depth, approximately 8 feet south of the ' <br /> original hole. Holes were pre-saturated on August 31, 1998. ,Percolation tests were performed on <br /> September 1, 1998 in accordance with EDH policy, copy attached. Field data sheets and a copy of the test <br /> 4 <br /> permit application arc also attached. <br /> ' <br /> 3.0 RESULTS <br /> FAll tests were performed using procedure #1 on the Policyfor Percolation Test Procedure (attached). At <br /> PERC 41, PERC #2, and PERC #3 the measured drop was 1116th of an inch in 30 minutes. At PERC #3 <br /> no drop was measurable. <br /> FTABLE 1 <br /> Summary of Percolation Test Results <br /> TEST NUMBER TEST LOCATION TEST HOLE DEPTH PERCOLATION RATE <br /> (inches) (min/inch) <br /> PERC #I See site map 18 480 <br /> PERC#2 See site map 36 480 <br /> PERC#3 See site map 36 Not measurable <br /> PERC#4 See site map 36 480 <br /> 4.0 LIMITATIONS AND SIGNATURE <br /> i <br /> k Results presented in this report are based on limited information obtained at the time of our site visits. <br /> R ' # <br /> Condor endeavored to determine as much as practical about the site using standard practice given our <br /> scope of services.
