Soil Sampling Tools - Large Bore Soil Sampler <br /> Large Bore Soil Sampling System . . . <br /> ' Soil samplers that remain completely sealed while being pushed or driven to depth. <br /> Typical Applications: Retrieval of Discrete Soil <br /> Samples at Depth Using Driven Probes L\ <br /> • Soil Sampling Beneath UST Sites <br /> • Studies or Chemical Dissipation with Soil Depth <br /> ' • Pesticide Studies <br /> • Hazardous Waste Site Investigations �\\ <br /> ' <br /> • I i <br /> Properly Transaction Surveys <br /> • Chemical Carryover/Residue Studies <br /> y <br /> The Large Bore (L8)Soil Sampler is used primarily as a <br /> m discrete interval sampler;that is,for the recovery of a sample <br /> c at a prescribed depth. In certain circumstances, it is also <br /> used for continuous coring. The Large Bore Sampler <br /> Geoprobe soil simplen feature linen that fit over <br /> m recovers a 22-inch long x 1-06-inch diameter(559 mm x the end of the tuning shoe. This feature,which <br /> '--t 27 mml core. Maximum core volume is 318 mL. <br /> e was pioneered by Geoprohe,allows soil to flow <br /> m into the liner without lodging behind the liner. <br /> Liners for the Large Bore Sampler are available in CAB(clear <br /> t ® plastic), brass,stainless steel,and PTFE I7eflone). <br /> r <br /> Calprobe's Large Bore Soil Sampler is perhaps the most <br /> ' popular direct push soil sampler in the United States today. <br /> It has achieved this Status by solving problems for field <br /> investigators. Think of the possibilities: Youneedto <br /> determine the distribution of contaminants at depth(i.e., 10, <br /> ' 20,and 30 feet 13,6,and 9 ml)—the Large Bore is your <br /> tool! Simply drive it to depth,open it,and recover a core. <br /> Easy driving.fast operation, <br /> minimal disturbance, no cuttings. <br /> ' Suppose the project requires T <br /> definition of contaminant <br /> concentration at a specific depth 1.125 in. 1.375 in. <br /> across the site.
