ground water pollution
Ground water is the water found in spaces between soil particles and rocks, and within cracks of the bedrock. Some ground water can be found beneath the land surface in most of the US. Because of its availability and general good quality, ground water is widely used for household needs and other purposes. Ground water is found in natural rock formations, which are called aquifers. For the most part, ground water comes directly from precipitation or surface water that infiltrates below the la ...
