The Ogallala aquifer, as shown on the map, covers a very large area in the central United States. The groundwater was deposited by ancient rivers millions of years ago and is used by farmers to water their crops. 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

It is affected because river water can seep into the ground and recharge the groundwater.
It is not affected because groundwater and river water are not connected.
