Direct push drills expand soil remediation options on projects

The science of environmental soil sampling and remediation spurred demand for a whole new set of tools. Geoprobe Systems of Salina, Kansas entered that market in 1987, with a series of small profile direct push drill rigs that provided an alternative to augers. Today the drills perform tasks that range from soil sampling, to direct injection of soil remediation chemicals such as oxidizers, and complex analyses of groundwater systems and contaminants.

The small size of the rigs allows them to be operated in close quarters, among industrial equipment or in challenging urban environments.

“The product line has developed many new applications, largely because clients have asked us whether the machines can do one thing or another,” says Greg Johnson, international sales coordinator with Geoprobe.

One development is the Membrane Interface Probe, which tests soils for volatile organic compounds (VOCs). When heat is inducted into the soil, it vapourizes VOC molecules, which penetrate a semi-permeable membrane that keeps groundwater out. The VOCs are then driven into a gas chromatograph using inert nitrogen gas.

The newest probe is the Hydraulic Profiling Tool (HPT), which measures the pressure required to inject water into the soil as the probe advances into the ground.
