1. Groundwater is defined as water that is found beneath the water table under Earth’s surface.

2. Groundwater Freshwater storehouse
98 percent of all the usable fresh water on the planet
60 times as plentiful as fresh water found in lakes and streams
valuable resource

3. travels through pores in soil and rock, in fractures, and through weathered areas of bedrock. 
Movement

4. Vocabulary Porosity: amount of pore space present in rock and soil
Permeability: ability of fluids to travel through the rock or soil
. A “high” permeability and porosity value means that the water can travel very quickly

5. Aquifer 
Body of water-saturated sediment or rock in which water can move readily
 unconfined aquifer is exposed to the surface of the land  
confined aquifer is an aquifer that has a confining layer that separates it from the land surface.

6. If the water is pressurized at a high enough value, when a well is drilled into the confining aquifer, water rises above the land surface. This is known as a flowing artesian water well.

7. Sinkhole

8. Recharge and Drawdown
Porosity and permeability affects the recharge rate of the groundwater.
 Drawdown: lowering of the aquifer near a pumping well.
creates voids in the bedrock
Sinkholes (cannot hold the weight of the material above and collapses)
