Ground Water

Ground water! What is it? Well it's basically self-explanatory and is any water that is held under ground. That is only a very simple definition of it though and well in fact ground water is very critical to every ones life locally and worldwide. Most of the water that you drink comes from ground water and not from lakes and rivers even though those are considered as a part of ground water components. Ground water has many components that it can be divided into and this paper will explain what ground water is, that negatives and positives of it, where is it and how it gets there.

Only in caves or near lava flow does the underground rivers and lakes occur. Instead ground water is usually held within pours of soil or rock material.

Groundwater is very beneficial to human life for several reasons. First, humans withdraw at about 40% of the public water supply on earth for everyday uses. Of that 40% that is withdrawn for everyday use 22% of it is fresh water that is sanitary enough to drink. One of those uses is very helpful for farmers and their irrigation systems to make crops, to help mankind be fed each and every day. In fact 34% of ground water is used
