Explain the consequences of groundwater depletion.

Correct Answer

verifed

verified

Removing more water from an aquifer than can be recharged is leading to land subsidence, or the settling of the soil as it dries out. As subsidence occurs, it can lead to a sinkhole. These form when an underground cavern collapses because there is not enough water in the cavern to support it. Saltwater intrusion can also occur when too much groundwater is removed from an aquifer. A decreased level of freshwater in the aquifer allows for seawater to back up into the depleted stream and aquifer.
