How far can the push tube sampler reach?

• A. Up to 25 Feet
• B. Up to 15 Feet
• C. Up to 30 Feet
• D. Up to 10 Feet

Answer: (A)

Push tube sampling uses long, rigid tubes that are pushed into the soil from the surface. The depth you can reach is limited by how long the tube string can be and how easily you can push it without causing tube bowing, excessive resistance, or disturbing the sample. Under standard field setups, a practical maximum reach is about 25 feet. Going deeper would require different equipment, like drilling or direct-push methods, because the longer and heavier tube becomes hard to push and can compromise sample integrity. So, the farthest reachable depth with a typical push tube sampler is around 25 feet.
