1.0 INTRODUCTION

Water is typically referred to as polluted when it is impaired by anthropogenic contaminants, due to these contaminates it either does not support a human use. Such as drinking water, or undergoes marked shift in its ability to support its abiotic communities, such as fish. Natural phenomena such as voleanoes algae blooms storms and earthquakes also cause major changes in water quality and the ecological status of water. Water pollution is a mojor global problem. It requires ongoing evaluation and revision of water resource policy at all levels (Internation down to death and diseases) (Baron, 1996). Water pollution accounted for the deaths of 1.8 million people in 2015 (Burkhardt, 2010).

The organization Global Oceanic Environment Survey (Goes) consider water pollution as one of the man environmental problems that can present a danger for the existence of life on earth in the nest decades one of the main concerns, is that water pollution, heart phytoplankton who produce 70% of oxygen and remove a large part of carbon dioxide on earth . the organization proposes a number of measures for fixing the situation, but the should be taken in the next 10 years for being effective (Faber et al., 1973).

Water pollution occurs when uncounted materials enter in to water, changes the quality of water (Alimman et al., 2016). And harmful to environment and human health. Water is an important natural resource used for drinking and other developmental purposes in our lives. Save drinking water is necessary for human health all over the world the world. Being a universal solvent, water is a major source of infection. According to World Health Organization (WHO) 80% disease are water borne. Drinking water in various country does not meet WHO standards. 3,1% death occur due to the unhygienic and poor quality  of water (Pawar et al., 2013).
