What is Groundwater?

Groundwater is water stored below earth's surface. The process that makes water groundwater is when water soaks through the ground. Ground water is also held underground in the soil or in pores & crevices in rock.

Porosity vs. Permeability

Porosity is the amount of space between soil particles & permeability is the materials ability to allow fluids to pass. High porosity equals lots of space between the soil where high permeability allows water to travel through soil easily. Low porosity equals little space between the soil where as low permeability doesn't allow water to travel through soil easily.

Types Of Aquifers

There are several different types of aquifer, such as, sand, gravel, sandstone, limestone, dolomite, & basalt flow but fractured igneous or metamorphic rocks are only marginal aquifers. The two main types of aquifers are unconfined aquifer & confined aquifer.

Groundwater Depletion

Groundwater Depletion is pumping water out of the ground faster than it is replenished over the long-term causes similar problems. Effects of Groundwater Depletion are earth quakes, ground subsidence, loss of water supply, drought, more energy to dig deeper for water, & salt water intrusion.

How do we pollute groundwater?

Pollution of groundwater happens when we put man-made products, such as gasoline, oil, road salts & chemicals into groundwater & it spreads throughout & causes it to be unsafe for humans to drink or use.
