Arsenic groundwater contamination and its health effect in villages along main stream of river Ganga, near Digha, Patna (Bihar)

We investigated the extent and severity of ground water arsenic contamination in Bind Toli and Nakta Diyara village along main stream of river Ganga, near Digha, Patna, Bihar State. We conduct a survey on health status of the people inhabiting the study area. A good number of people in these villages had been found to have various type of skin problems which appear, to all probability due to presence of arsenic in their drinking water source. Ground water samples collected from seventeen different location of Bind Toli Village and 24 sample from Nakta Diyara village. All the sample were tested on an UV-Spectrophotometer by a standard silverdiethyldithio carbamate (SDDC) method and result was compared with water quality standard by Bureau of Indian standard (IS- 10500;1991).
