• floodplains

• wetlands

• coastal areas

Withdrawing too much water from an aquifer can cause all of the following except

• freshwater contaminated with saltwater
• land subsidence
• sinkholes
• drought

Where do we typically see saltwater intrusions into freshwater aquifers?

• On the great plains

• In the mountainous regions

• In coastal areas

• Along rivers

Desalination is

• removing salt from water
• removing oil from water
• removing toxic chemicals from water
• adding salt to water

The disadvantage of desalination water is that...

• It is expensive and produces briny wastewater

• It can be used in areas with little freshwater

• It produces water that is not safe to drink.

• It is not a real thing.
