III . DESCRIPTION OF FIELD WORK <br /> Using the centerline of Byron Road, a line parallel to said road <br /> was surveyed to estabish a staked reference line for the location <br /> of nine soil borings, 200± feet apart. The reference line stakes <br /> were located by engineer' s stations 10+00 through 28+00. Station <br /> 10+00 is marked by a spike placed in the west edge of the road surface <br /> of Corral Hollow Road, approximately 175 feet south of the centerline <br /> of Byron Road, the right-of-way width �of which is 50 feet. Beginning <br /> with Station 10+00, stations were marked at 200± feet intervals <br /> through Station 28+00. Station 28+�00 is located near the west <br /> property line of the parcel of and. owned by Sunboro Development <br /> being east of the north-south alignment of the West Side Irrigation <br /> {~ District's canal . The soil borings sere drilled 25 feet north of <br /> the staked reference line (125 feet south of Byron Road's south <br /> boundary) to assure that the relocation of the soil borings could <br /> be made if necessary. <br /> On September 8, 1988, North Valley Drilling Company, Lodi , California, <br /> California License #418834, started drilling soil borings at the <br /> Sunboro Development site, following la work plan approved by the <br /> San Joaquin Local Health District, Hazardous Waste Division, 1601 <br /> Hazelton, Stockton, California. <br /> The firm of Adleson, Hess, Christense & Kelly, San Jose, California <br /> hired Terrestrial Technology, Inc. ofI Davis, California (California <br /> Civil No. 17381) to provide technical and engineering services for <br /> this work. Terrestrial Technology, Inc. hired North Valley Drilling <br /> Company, Lodi , California (California License # 418834) to drill <br /> the soil boring then backfill and seal the bore holes. Terrestrial <br /> Technology, Inc. prepared the soil Isamples and delivered them to <br /> Eureka Laboratories, 3401 La Grande Boulevard, Sacramento, California, <br /> a California Certified iaboratory.1 During the soil boring, <br /> representatives of the Sunboro Development Corporation were present <br /> most of the time. <br /> Drilling started on September 8, 1988 and was completed on September <br /> r 12, 1988. The San Joaquin Local Health District staff observed <br /> sealing of the borings on September 12, 1988. <br /> Following is a brief description of the soil boring, logging and <br /> profile of soil from each drill hole, sampling and transport for <br /> laboratory analysis and the laboratory analysis results. <br /> F <br /> F <br /> F <br /> F, <br />
