The SoilBED facility is supporting environmental applications (contamination detection) and civil infrastructure applications. The SoilBED design allows us to mold background media (soil, concrete, asphalt, etc.) at preset conditions with known composition and characteristics. The objective is to use SoilBED to verify computational tools that are being developed for DNAPL source zone delineation and characterization using ultra-wideband Cross-Well Radar (CWR). The imaging system envisioned in the field consists of Radio Frequency (RF) antennas placed in a regular array of widely spaced boreholes at depths that could reach few hundred feet. This is an innovative technique that will provide state of the art imaging of DNAPLs in the subsurface. Validation of such innovative techniques would be difficult without controlled facilities such as SoilBED. Furthermore, the NU facility will be used to assess the performance of the antennas/sensors and also the evaluation of the wide-band geophysical properties of soils.
