Asked by M00n

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)

Reason: Hard rock requires a percussion (pounding) drill; because the water table is shallow a suction-type jet pump (aboveground) can lift the water.
