Mining and its allied activities may affect the standards of surface water in the adjoining areas. Present investigation has been carried out in opencast mining and non-mining affected areas of Kolayat district Bikaner western Rajasthan for heavy metal evaluation in surface sources of water. During monsoon season sixteen samples of surface water sources of study area were collected by standard methods and evaluated for Iron, Manganese, Copper and Zinc by Atomic Absorption Spectrophotometer method and Sodium and Potassium by Flame photometer. The analyzed results were interpreted and compared with BIS of drinking water. Analysis of results and data interpretation reveals that the heavy metal assemblage in surface water sources of study area are below the recommended limit of drinking but mining affected areas have higher concentration than non-mining areas. Hence it is suggested that the mining and related activities in study area should be properly planned and not to disturb the natural drainage system of local talav, nadi, johad, sarovar etc. So that the water of surface bodies could maintain its quality for drinking purpose of local peoples. It is our duty to preserve and protect to natural resources of water for better future of coming generations and for humanity. Copyright@ International Science Community Association
