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?
