Groundwater Quiz T6EX2

The Ogallala aquifer, as shown on the map, covers a very large area in the central United States.

The groundwater in the aquifer is not being replenished as quickly as it is being used. Which best describes how human actions can beneficially influence the Ogallala aquifer to keep groundwater access?

• Water conservation measures

• Drilling more water wells

• Making existing wells deeper

• Use air sparging
