Arsenic contamination of drinking water supplies is a world-wide problem of increasing concern. The source of arsenic in natural water is most often the leaching of geologic materials. Thus, elevated arsenic concentrations are more prevalent in groundwaters than in surface waters. Although less common, there are some cases of significant concentrations of arsenic in surface waters associated with inputs of hydrothermal waters or historical or current mining. This paper examines some international experiences with arsenic occurrence, exposure, and removal. The problem of groundwater contamination by arsenic in West Bengal, India, and the experience with full-scale treatment for arsenic removal in Chile are highlighted. Recent investigations of the effects of source water composition on the efficiency of treatment technologies for arsenic removal are discussed.
