Abstract
One of our most important natural resources is water, but like many of our other resources it is affected by the human activity and surrounding environment. The water that we use for drinking, crop irrigation, household uses and many other things should be healthy so that it provides good health. For its needs, in fact over 1/3 of earth’s population relies on ground water, including 99% of the rural population in the U.S. ground water also moves around a lot, not only underground, but also as a source of discharge in to earth’s stream, lakes rivers and oceans. But just because it’s underground does not mean that ground water is safe from many of the same environmental issues that surface water faces. Ground water is the receptor of large quantities of waste products i.e. domestic, human, animal, industrial and agricultural which causes deviation in quality of water All potable water viz. open well, tube well, tap and canal are becoming polluted due to wastes waters of sewage, indiscriminate use of pesticides chemical fertilizers dumping off radioactive wastes in agriculture and public health programme. The influence of waste water and pesticides on drinking water would depend on its characteristics resistance to biodegradability before reaching these water sources. A number of studies have been carried out on water quality deviation due to pollution of water throughout the world.
