' introduction •Geoprobe Machines • <br /> What is a Geoprobe? <br /> ' o A Geoprobe is a hydraulically-powered, <br /> �• percussiontprobing machine designed specifically <br /> for use in the Environmental Industry. The first <br /> Geoprobe was bush for the Environmental <br /> Protection Agency in 1986. <br /> Soil probing techniques can be thought of as a j <br /> subcategory of what are commonly referred to as IL . <br /> 'Direct Push"techniques_ Direct push refers to <br /> tools and sensors that are inserted into the ground it sc �: - ■ r <br /> without the use of drilling to remove soil and make <br /> a path for the tool. A Geoprobe relies on a �I <br /> relatively small amount of static(vehicle)weight i <br /> combined with percussion as the energy for <br /> advancement of a tool string. <br /> ' Using a Geoprobe,you can drive tools to obtain <br /> continuous soil cores or discrete soil samples. You <br /> can drive samplers to obtain groundwater samples Geoprobe Model 5400(left)and Model 4200 <br /> or vapor samples.
