Chromium and arsenic have been identified as cocontaminants in wastes from wood preservative manufacture, paint and ink manufactures, petroleum refineries, as well as some municipal wastewaters. Inadequate storage and improper disposal practices of chromium and arsenic have caused many incidences of soil and groundwater contamination in industrialized areas. Both chromium and arsenic represent potential threats to the environment, human health, and animal health due to their carcinogenic and toxicological effects. Hexavalent chromium Cr(VI) and arsenic have been considered as important priority pollutants worldwide owing to numerous health problems arising from groundwater contaminated by these two pollutants. Therefore, the World Health Organization (WHO) has established a provisional guideline of 10 µg/L for arsenic and 50 µg/L for Cr(VI) in drinking water. Recent public concern regarding arsenic and Cr(VI) in drinking water has promoted the investigation of treatment technologies with the potential to remove them simultaneously to levels well below the drinking water maximum contaminant level.
