Arsenic in drinking water, according to studies of National Academy of Sciences, causes bladder, lung and kidney cancer, harming the central and peripheral system of the nervous system. The article published by Allan H. Smith establishes the proposition that contaminated water can in fact have a mass concentration of arsenic in Third-World country water. “High levels of arsenic tend to be found more in ground water sources than in surface water sources of drinking water.” According to the USGS, 240 million people get their water from ground water which establishes the idea that 240 million might have a slight chance of obtaining water containing arsenic. Using iron oxide nanoparticles, and placing them in contaminated water, we are hypothesizing that the iron oxide’s magnetic pulse will attract to the arsenic having the nanoparticles and the arsenic together. We will use a centrifuge to separate the water from the particles and remove the particles from the water. We will use a method for screening water and detect if there is still any arsenic in the water and if this test is successfully completed, then there were would be a cost sufficient way of removing arsenic from water.
