Abstract: Globally, ground water is contaminating by arsenic continously, which needs economic treatment and remediation technologies. Physical, chemical and biological treatment methods have been developed, that include different kinds of filters, bucket type units, fill and draw, kalshi etc. The remediation methods discussed are air oxidation, reactive barriers, utilisation of deeper aquifers and sanitary protected dug wells. To the best of our knowledge no technology is available capable to remove arsenic from water at efficient, economic and commercial levels. Therefore, fast, efficient and economic arsenic removal technologies are required. Attempts have been made to suggest the future technologies of arsenic removal.
