Arsenic occurs in water in many parts of the world mainly as a result of natural sources but also as a consequence of anthropogenic activities. Consuming water contaminated by arsenic can cause skin and bladder cancer and cardiovascular disease Therefore, the US and WHO maximum contaminant level (MCL) for arsenic in drinking water is 10 ppb but concentrations higher than this occur throughout the world leading to a tremendous need for development of cost efficient methods for arsenic removal. There are currently many methods for remediating arsenic-containing water that could be utilized not only to purify water for drinking but potentially could be used to prevent contamination of food by treatment of agricultural water. The various methods for removal of arsenic and their benefits and drawbacks will be reviewed in this presentation, culminating with a discussion of novel high capacity sorbents for removal of arsenic from water.
