Arsenic exposure on human society is potentially grave and may extend from general malaise to death. Arsenic in water is a vital problem in many countries around the world including Bangladesh, India, and China etc. Arsenic patients of the study area are suffering from several clinical and non-clinical symptoms. Arsenic contamination in ground water and related health hazards has serious concerns in the study area. Excessive intake of arsenic in human body causes skin pigmentation, skin cancer, cardio-vascular diseases, lung and liver carcinoma etc. In the study area levels of arsenic contamination in ground water in higher than the WHO limit (10μg/L). All surveyed villages of the study area are situated in the flood plain region of river Brahmaputra. The aim of this research paper is to investigate the spatial distribution pattern of arsenic contamination in the study area. Another aim is to study about arsenic toxicity. Water samples were collected from six selected villages that are Gopeswar and its neighbouring villages to know the level of arsenic contamination in groundwater. Samples were collected from tube wells used for drinking, cooking and other household purposes. Based on field data arsenic distribution map have been prepared with the help of Geographical Information System. The coordinates of the locations were recorded using Geographical positioning System machine. It was found that Gopeswar and its neighbouring villages have arsenic contamination more than World Health Origination limit i.e. 10 ppb.
