Does a split spoon require the use of a drill rig?

A split spoon is a type of sampling equipment that is primarily used in conjunction with a drill rig to collect soil samples during subsurface investigations. The design of the split spoon allows it to penetrate soil efficiently while capturing a core sample, making it ideal for assessing soil conditions and potential contaminants in UST site assessments.

While some sampling methods can be performed manually, the split spoon method requires the application of specific drilling techniques and equipment, typically provided by a drill rig, to achieve the necessary depth and obtain representative soil samples effectively. The drill rig provides the necessary force and rotational torque to allow the split spoon to penetrate the ground adequately, which would be challenging to accomplish manually, especially at depths typically required for UST assessments.

The other choices might suggest scenarios where a split spoon could be used without a drill rig, but these are not standard practices in site assessments. Therefore, the use of a drill rig is essential for utilizing a split spoon effectively in most cases.
