Abstract
A recently developed direct-push technology (hydraulic hammer rig) was used for vadose zone characterization to 36 m depth adjacent to a mixed-waste disposal site in the 200 West Area at the U.S. Department of Energy's Hanford Site near Richland, WA. The capabilities of the hydraulic hammer rig in terms of time required to reach target depths, depth of penetration, and ability to obtain representative soil samples were evaluated and compared to two other characterization techniques used at the site (Enhanced Access Penetration System and cable tool drilling) in similar geologic conditions. The hydraulic hammer rig technology took several hours to reach the Cold Creek unit calcic paleosol stratum versus days for the Enhanced Access Penetration System and weeks to months for cable tool drilling. The hydraulic hammer rig is an innovative and rapid vadose zone drilling technology with proven capabilities to penetrate, characterize, and sediments down to about 36 m depth without bringing soil cuttings to the surface.
