Use of Push-Driven Technology
Also known as direct-drive, drive-point or direct-push, push-driven technology refers to tools used to investigate sites by driving, pushing, and/or vibrating small-diameter hollow steel rods into the ground. Sampling tools can be attached to the end of the steel rods to collect soil, soil-gas and groundwater samples. For purposes of this fact sheet, push-driven technology also includes push-driven equipment that is capable of using an auger tool (similar to that used for a conventional monitoring well) to install pre-pack monitoring wells.
