Water as a gift of nature is generally believed to have no enemy. Despite the abundance of fresh water on the earth, many regions are in deep crisis of water shortage due to there being polluted by human activities, or the ever increasing demand by industrialization and high population growth. Thus, groundwater is the alternative source of fresh water in areas where surface water is polluted or particularly in arid and semi-arid region of the world. However, the ground water that is presently rely on is generally been grossly polluted by various sources e.g. solid waste Waste is defined as any substance or object discarded for any reason, whether part or all and such substance may be recycled e.g. rubbish, trash, scraps, tiles, bottles, cans, papers, chemicals, slugs, machine parts, scrap metals etc. Once waste is deposited at the landfill (dumpsite) pollution can arise from the migration of both gas and leachate. There are three broad types of contaminants present in leachates that can pollute groundwater and subsequently affects public health. These are hazardous chemicals, conventional and non-conventional contaminates. The cost of cleaning up groundwater contaminated by Municipal Solid Waste landfill leachates require large sum of money and technology, which are presently not available in our society. Thus it is important that efforts are geared towards preventing pollution that will arise from leachate.
