What is Groundwater??

Groundwater is precipitation that has come down and has soaked into the soil, found underground.

Porosity vs. Permeability

Porosity: The amount of space in between soil particles, determines how permeable something is.

Permeability: A materials ability to allow fluids to pass through it.

Aquifers

There are two different kinds of aquifers:

Unconfined Aquifers- in an unconfined aquifer water can flow freely

Confined Aquifers- in a confined aquifer the water is restricted

Anatomy of an Aquifer

Water Table

Zone of aeration- Region in the ground in which pore spaces are filled with air, and sometimes water.

Zone of saturation- The area beneath the water table where all pore spaces are completely filled with water.

Water table- The level below which the ground is saturated with water.

Aquiclude- An impermeable body of rock or stratum of sediment that acts as a barrier to the flow of ground water.

Aquifer- A body of permeable rock that can contain or transmit groundwater.

What kind of effects can depleting our groundwater supply cause?

If our groundwater supply began to decrease it would cause many problems including, land subsidence, deterioration of water quality, lowering of the water table, and reduction of water in streams or lakes.

Pollution

We pollute groundwater when man-made products like chemicals, gasoline, road salts and oil get in our groundwater and cause it to be unsafe for our use.
