A hydraulic hammer is used to drive a hollow rod into the soil beneath and around Hanford’s radioactive waste tanks. Monitors and sensors can then be lowered into the rod to help determine the nature and extent of contamination.

An Interim Surface Barrier was installed over portions of Hanford’s T Farm to demonstrate its effectiveness in preventing rain and snow melt from driving contaminants toward the water table.

Steel rods are used in a technique known as Surface Geophysical Exploration or SGE. The rods are inserted in a grid pattern and a computerized control system passes during between them, mapping differences in how the soil responds. The technology produces a 3-dimensional image of a waste plume deep in the soil.
