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)

GPT-4o mini · Answer

For this scenario, the most suitable choice would be:

a percussion drill with a jet pump.

A percussion drill is effective for breaking hard rock, as it uses a pounding action, making it ideal for the hard rock conditions described. A jet pump can effectively lift the groundwater to the surface when the water is not too far below the surface.

Therefore, the correct response is: a percussion drill with a jet pump.
