ABSTRACT The problem of trace metals in the water is becoming the major source of contamination specially Arsenic. This is a most commonly trace metal found on the earth. The presence of Arsenic in ground water may originate from chemical reactions, due to weathering of rocks, due to mining activities, industrial effluents or use in agricultural sectors as a insecticides or a pesticides. Arsenic levels above permissible limits of 50 ppb in groundwater have been reported from many parts of the world. It has been an unforeseen consequence of a large-scale programme of replacing contaminated surface water sources by ‘safe’ groundwater. Arsenic in groundwater was first detected in 1983 following reports of many people suffering from arsenical skin diseases. In Bangladesh, West Bengal region of India [1] inner Mangolia region in China, Thailand, Argentina, Ghana, Japan, Chile, Mexico, Hungary, Romania, U.S.A. [2] and Taiwan [3], millions of people are suffering from ill effects of excess arsenic intake. The permissible limit of arsenic in drinking water is 50 ppb [4, 5], but arsenic up to 3.4 mg/l has been reported in some regions of the world. Chronic poisoning of Arsenic is manifested by General muscular weakness, loss of appetite, nausea, inflammation of mucous membranes in the eyes, nose and larynx, skin lesions, gastrointestinal injuries, kidney damage, circulatory collapse, respiratory failure and neurological disorders [6] vascular system damage, gangrene, lung, bladder, lymph glands, prostate, kidney and liver cancers. The skin lesions caused by Arsenicosis are confused with leprosy. Affected villages are treated much like isolated leper colonies. Sufferers are barred from social activities and often face rejection, even by immediate family members. Thus, it is urgently needed to find alternate sources of safe drinking water or to develop some feasible technique for Arsenic removal from contaminated water. Keywords:-Trace metals, Arsenic, Groundwater, Adsorption.
