What is an Aquifer? part of Videos:Video Gallery
This video describes the basic characteristics of two types of aquifers and identifies four types of geological units that make up many of the aquifers in the US. We compare and contrast unconfined and confined aquifers and show the distribution of aquifer systems composed of sand and gravel, sandstone, carbonates (limestone), and fractured igneous and metamorphic rocks. On the basis of the maps we show you, what is the most likely composition of your local aquifer system?

Porosity and permeability part of Videos:Video Gallery
This video briefly introduces the concept of groundwater before explaining how two properties - porosity and permeability - combine to determine the availability of groundwater and the ease with which it travels through rocks and sediment. We show simple bench-top demonstrations to illustrate each property and we calculate what a reasonable porosity value would be for common sediments such as sand and gravel. Finally, we discuss which rocks would best serve as sources of groundwater and which are likely to be barriers to groundwater flow.
