1 <br /> Soil Sampling Tools - Large Bore Soil Sampler <br /> 1 <br /> Large Bore Soil Sampling System . . . <br /> 1 Soil samplers Char remain completely sealed while being pushed nr driven to depth. <br /> Typical Applications: Retrieval of Discrete Sail <br /> Samples at Depth Using Driven Probes <br /> 1 • Soil Sampling Beneath UST Sites <br /> • Studies of Chomical Dissipation with Soil Depth <br /> • Pesticide Studies <br /> 1 <br /> • Hazardous Waste Site Investigations <br /> 1 • Property Transaction Surveys <br /> • Chemical Carryover(ttesidue Studies <br /> 1 e, The Large Bore(L13)Soil Sampler is used primarily as a ! `` <br /> JA discrete interval sampler;that is,for the recovery of a sample <br /> at a prescribed depth. In certain circumstances,it is also <br /> 1 used for continuous coring. The Large Sore Sampler <br /> "robe soil sa splen feature liners that tit over <br /> m rot, vers a 22-inch long x 1.0&inch diameter(S59 mm x the end of the cutting shoe_ This feature,which <br /> e27 mm)core. Maximum core volume is 318 mL. w s pioneered by Geoprobe,allows soil to flow <br /> into thv liner without lodging behind the finer. <br /> Liners for the large Bore Sampler are available In CAB (clear <br /> ' plastic), brass,stainless stool,and PTFE(Teflone). <br /> Q-vrobe's Large Bore Soil Sampler is perhaps the most <br /> popular direct push soil sampler in the United Statestoday. <br /> 1 it has achieved this status by solving problems for field <br /> investigators. Think of the possibilities: You need to <br /> &wrmino the distribution of contaminants at depth(i.e., 1 D, <br /> 20,and 30 Feet 13,6,and 9 ml)---the Large Bore is your <br /> 1 wlI Simply drive it to depth,open it,and recover a core. <br /> Easy driving,fast operation, <br /> minimal disturbance, no cuttings. <br /> 1 Suppose the project requires <br /> definition of contaminant <br /> concentration at a specific depth 1.125 in. 1.375 in. <br /> across the site.
