Arsenic Treatment in Groundwater in Mekong Delta Using Laterite Absorbent

Arsenic contamination in groundwater has led to pandemic influenza and many disease in Viet Nam and its neighbour country. It is estimated that about 57 million people in the world are affected by Arsenic contamination in drinking water. In Viet Nam, especially in Mekong River Delta, the Arsenic was detected in drinking water is up to 3000 μg/l, many times higher value allowed by the World Health Organization (WHO) of 10 μg/l. In this study, the laterite absorbent was used to treat Arsenic in groundwater in Mekong River Delta in Viet Nam. It is determined that laterite is a powerful absorbent for Arsenic removal in groundwater.
