Groundwater topics include: Sources and zonal distribution of groundwater, water bearing qualities of rocks, aquifer types and functions, different rocks as aquifer and groundwater considerations.
Groundwater is water that's stored in the pore spaces of soil and rock, and in the fractures of rock formations. It's a major source of freshwater, accounting for about 30% of the world's readily available freshwater.
Groundwater is precipitation that's seeped through the soil and collected in underground spaces. It can move through an aquifer and resurface through springs and wells.
Groundwater can contain dissolved minerals and gases that give it a tangy taste. The most common dissolved mineral substances are sodium, calcium, magnesium, potassium, chloride, bicarbonate, and sulfate.
Groundwater is stored in aquifers, which are bodies of porous rock or sediment that are saturated with groundwater. Aquifers can be extracted for consumption or other uses.
There are three types of groundwater: Aquifers Hand-dug wells Artesian wells: Artesian wells are wells that naturally have water flowing to the surface of the ground.
