| 説明 | Meghan Riehl, a Savannah Corps geologist, takes a groundwater reading of soil material at a site near Fort Jackson, South Carolina Jan. 26. Soil was extracted using the TerraSonic drill rig—a piece of high-tech machinery that is the only one of its kind within USACE. The drill can be used to perform subsurface and geotechnical investigation projects on the toughest terrains throughout the nation. |
