Arsenic is a toxic metalloid highly diffused in groundwater because of natural and anthropogenic factors (mainly deriving from mining activities and pesticides). Inorganic arsenic compounds are classified by the International Agency for Research on Cancer (IARC) in Group I (proven carcinogen). Groundwater concentration of As may vary from 0.5 to 5000 μg/L taking into account more than 70 Countries around the world. The most polluted groundwater of the planet was identified in late 1990s in Bengal delta (Bangladesh and Indian region West Bengal).
