Abstract
High arsenic groundwater has emerged as a niggling environmental problem in the recent decades. Elevated levels of groundwater arsenic (>>50ppb) in the Bengal Delta Plain (BDP) threatens the lives of millions of people. The present study deals with the adsorption pattern of AsO 4 3- and AsO 3 3- , the predominant arsenic species in groundwater using red earth for the supply of potable water. The mineralogical study of red earth exhibits the predominance of iron and aluminium secondary phases. Cost calculated for the transportation of red earth approximates to US$16/ton/1000km whereas the treatment process estimates to US$0.6/100L contaminated water. Batch and column studies reveal the promising role of red earth in removing arsenic from water.
