Clean+Water+Tech

__//**Clean Water Technology**//__ **Prezi** []**Video Presentation** **Major Map With Focus Area** G.A.C is an acronym for granular activated carbon this material can be used to remove contaminants in well water that have a positive charge. The testing at ASU is now to add a surfactant layer to the carbon in order to remove the negatively charged arsenic that is a problem in well water which is available to those who dont have access to communities without a water treatment center. These communities can be those of rural or tribal land and also people in underdeveloped countries which is the focus of this project to impact and help those who cant get clean water but have no choice but to use the contaminated water.

The G.A.C material is similar to a fish tank filter and can be used on a various size scale to fit the needs of the amount of people needing clean water. It is also easy to use and maintain which is key when trying to bring a product to the develpong world and you dont have to have an experienced person maintain the system. The low cost was the most attractive reason this was choosen to be tested because it can be brought to places where monetray means are low but the need is very high.

The issue with this technique though is that the surfactant is "leaching" from the surface and becoming a contaminant itself. Which means that the surfactant is coming off of the carbon and re-enterin the water that was cleaned. That is why this product hasnt been pilot or field tested because of the risk.
