Introduction — Geoprobe Machines <br /> 1 <br /> What is a Geoprobe? <br /> A Geoprobe is a hydraulically-powered, <br /> G percussion/probing machine designed specifically <br /> for use in the Environmental industry. The first <br /> Geoprobe was built for the Environmental <br /> Protection Agency in 1988, <br /> Soil probing techniques can be thought of as a i�• <br /> subcategory of what are commonly referred to as et <br /> "Direct Push"techniques_ Direct push refers to <br /> tools and sensors that are inserted into the ground it F '�- f: <br /> without the use of drflling to remove soil and make <br /> a path for the tool. A Geoprobe relies on a rs r i <br /> ' relatively small amount of static(vehicle)weight r <br /> combined with percussion as the energy for <br /> advancement of z tool string. <br /> Using a Geoprobe,you can drive tools to obtain <br /> continuous soil cores or discrete soil sarnples. You <br /> can drive samplers to obtain groundwater samples Geoprobe Model 54013(left)and Modes 4200 <br /> or va por sam ples.
