Groundwater vs surface water.
Water table is the term for the upper surface of the zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with groundwater, [1] which may be fresh, saline, or brackish, depending on the locality. It can also be simply explained as the depth below which the ground is saturated.
Groundwater is the portion of water present below the Earth’s surface in pore spaces of soil/unconsolidated rocks and in the fractures/fissures of crystalline rock formations, etc. Groundwater constitutes about 30% of the world’s freshwater supply, which is about 0.76% of the entire world’s available water (Gleick 1993).Groundwater …Ground Water and Surface Water A Single Resource.

In simplest terms groundwater is what its name implies: water in the ground that fully saturates pores or cracks in soils and rocks. Water underlies the Earth's surface almost everywhere – beneath oceans, hills, valleys, mountains, lakes, and deserts. It is not always easy to get to or clean enough for use without treatment, but it exists ...
As the field of hydrogeology matures, the strong interactions between groundwater, surface water, water chemistry, soil moisture and even climate are becoming more clear. California and Washington both require special certification of hydrogeologists to offer professional services to the public. Twenty-nine states require professional licensing ...Looking at water, you might think that it's the most simple thing around. Pure water is practically colorless, odorless, and tasteless. But it's not at all simple and plain and it is vital for all life on Earth. Where there is water there is life, and where water is scarce, life has to struggle or just "throw in the towel."
Groundwater Temperature's Measurement and Significance. Springs can develop where either unconfined or artesian aquifers crop out at the surface. Springs develop where streams have incised so deeply that the aquifer is exposed along the valley walls where spring lines develop. A spring is groundwater becoming surface water.
1.Ground Water- contained under subsurface layer of rocks and soil. Surface Water- found in rivers or lakes or surface cavities. 2. Ground Water- maintained in a constant temperature.
