Water is the readily available source for drinking, agricultural and industrial uses. The problem of heavy metal contamination in water bodies is wide spread. The most dangerous among them are arsenic, lead, mercury, zinc, copper etc. Water contamination with arsenic is having a world wide concern .Arsenic is a ubiquitous element being distributed in atmosphere, aquatic environment, soil and sediments and organisms. Arsenic is a group V metalloid which is tasteless, odourless and brittle in nature. It is grey or tin white in colour and remains as oxide, hydrate, sulphide, arsenite and arsenate. It also exists in the lava of volcano. Due to the carcinogenic property of arsenic, environmental regulatory agencies around the world are reviewing the maximum contamination level in drinking water, which is the main source of arsenic intake. The Public Health and Environmental Engineering Organization (CPHEEO) has prescribed the limit for arsenic in drinking water as 0.05mg/l.
