Water is generally obtained from two principal natural sources: surface water such as fresh water lakes, rivers, streams and groundwater such as borehole water. Water is one of the essentials that support all forms of plant and animal life and it has unique chemical properties due to its polarity and hydrogen bond which means it is able to dissolve, absorb, adsorb or suspend many different compounds. Groundwater is the major source of drinking water in the world because of its availability and constant quality [1-3].
