What is the water table?

Back

The water table is the top boundary of the zone of saturation in an aquifer, which can fluctuate based on precipitation and the amount of draw from wells.

How do people extract groundwater?

Back

People extract groundwater by drilling wells and pumping water out of the ground.

What does permeability measure in an aquifer?

Back

Permeability measures how easily water can flow through a substance, such as an aquifer.

What is the difference between an unconfined aquifer and a confined aquifer?

Back

An unconfined aquifer has no upper layer restricting water flow, while a confined aquifer is bounded above and below by impermeable layers.

Front

What factors can affect the water table level?

Back

The water table level can be affected by precipitation, evaporation, and the amount of water drawn from wells.

What is an aquifer?

Back

An aquifer is a geological formation that can store and transmit water, allowing it to be extracted for use.
