This letter presents the results of our <br /> study. <br /> 3 <br /> I PROPOSED DEVELOPMENT <br /> A new winery is being constructed on a rectangular shaped, 150 acre parcel located on the <br /> west side of Jacob Brack Rd., approximately 2500 feet north of Turner Rd., Lodi, California. It is <br /> proposed to dispose of the winery waste effluent,estimated at 10,000 gal/day,by spray irrigation to <br /> two areas totaling 30 acres (see attached Location Map, Plate No. 2). <br /> Ii SOIL PROFILE <br /> A total of 4 test holes were excavated to a depth of 15 feet over the proposed effluent <br /> application area. The purpose of the test holes was to determine the general soil profile of the area <br /> and to obtain ground water samples for nitrate testing. Test holes were excavated with a truck <br /> mounted drill rig utilizing 4.5-inch diameter continuous flight auger. For approximate location of <br /> + the test holes see the attached Location Map, Plate No.2. The test holes were logged and a <br /> description of the soils encountered in each hole is contained on the Log of Test Boring sheets,Plates <br /> No. 3'through 6. <br /> The upper 4 to 9 feet of soil encountered in the test holes consisted of a loose to medium <br /> Y dense sandy silt. This was underlain by a medium dense to dense silty sand which was slightly <br /> cemented in places and continued to the maximum depth explored of 15 feet. For a more detailed <br /> description of the soils encountered in the test holes see the log sheets. <br />
