Ground or subterranean water is water that is found below the earth’s surface. Groundwater is simply water under the ground where the soil is completely filled or saturated with water. This water is also called an “aquifer.”
The following are four types of ground water:
- Connate water. It may also referred as fossil water. This is water trapped in the pores of the rock during the formation of the rocks. The chemical composition of water changes with the changes that the rock undergoes. Most connate water is saline.
- Meteoric water. This refer to ground water which originate from rainfall and other forms of precipitation such as hailstorms and snow fall. It is as the result of precipitation water seeping into the ground
- Juvenile water. It is also referred to as magmatic water. This is water that is brought closer to the earth’s surface due to volcanic activities. It usually has high mineral content
- Oceanic water. This is groundwater that results from the seepage of groundwater into the ground. It is common in the coastal areas where ocean water seeps horizontally into the ground from the ocean
