Water
is a necessity to man and his environment; it has existed
throughout the history of the earth crust or even before the
existence of man. Man uses water for the following
activities: irrigation, power generation and domestic
activity. There are two natural sources of water: rain and
ground waters. It is found in rivers, wells, lakes and
streams. The activities of human and natural phenomena
constantly pollute the sources of water and affect water
quality. Water pollution arises as a result of waste and
sewage disposal into the environment and rivers by
industries, hospitals and use of materials such as fertilizers
by farmers. These disposed materials often contain radio
nuclides [3].
