A company has been hired to drill a well to mine for groundwater. The rock in the area is very hard, so the drill used must be able to pound the rock to break it apart. Fortunately, however, the groundwater is not too far below the surface, so a suction pump can be used to bring the water to the surface. What type of drill and pump should the company use?(1 point)

Question

GPT-4o mini · Answer

For drilling in hard rock to access groundwater, the company should use a percussive drill, specifically a rotary percussion drill or dth (down-the-hole) hammer drill. These drills are designed to pound the rock and break it apart effectively.

For bringing the water to the surface, they should use a submersible pump. Submersible pumps are designed to operate underwater and can efficiently lift water from the well to the surface.

In summary, the company should use a rotary percussion drill along with a submersible pump for this project.
