An overview of arsenic removal processes

Several methods of treating water for arsenic reduction are being discussed. In general: each of these processes is capable of providing acceptable service under the correct circumstances. The challenge is to determine which process goes with which set of circumstances. Considering the probability that the maximum contaminant level (MCL) for arsenic will be reduced substantially, it is likely that many water purveyors will need to begin arsenic reduction in the next few years. Hopefully, this paper will provide some direction in their search for selecting an appropriate treatment process.
