discuss why groundwater is one of our most important sources of fresh water. how is a groundwater reservoir recharged? when is use of groundwater unsustainable (4 points)?



Answer :

Groundwater contributes to the flow of our rivers. Groundwater is used for drinking water by nearly half of all Americans, but it is primarily used for crop irrigation and food production.

Groundwater is protected from contamination because it is stored beneath the Earth, so the water quality is far superior to obtaining drinking water sources from surface waters. By rerouting water across the land surface, groundwater can be artificially recharged. The development and use of groundwater to meet current and potential beneficial uses without having caused undesirable environ - mental or sociocultural consequences is referred to as groundwater sustainability.
