The solution is cheap since the sources of graphite could include the waste produced by graphite mining companies that still contains a significant amount of graphite. And the researchers believe that it is possible to modify the graphite oxide to pick out particular pollutants and therefore tailor the super sand to specific areas that might be having trouble with certain water-borne diseases or pollutants.
