Description :
Ground water is extensively being used as one of the major source of drinking water in the developing Countries. It is generally considered as the safest water source as far as pollution is concerned. However recent increase in unplanned urbanization without any adequate provision for disposal of the generated wastes and improper and incomplete treatment of waste by industries, agricultural practices and domestic users has increased the stress on water reservoirs of getting contaminated. Evaluation of ground water samples from Makardhokda Mines Housing Colony, Makardhokda was carried out for a period of one year (Oct-2010 to Sept-2011). Water samples were collected from five different sites of Makardhokda Mines within a range of 5Km area around the mines and analysed for physico-chemical characteristics (Temp, pH, Conductivity, Alkalinity, Chlorides, TDS, DO, COD, SO₄), bacteriological parameters (Total coliform count and fecal coliforms), and toxic metal (Ca, Mg, Mn, Fe, Arsenic). It was found in the present investigation that the pH of water samples was slightly alkaline. The total hardness of water samples was larger than desirable limit. The total alkalinity and COD was also larger the desirable limits. Bacteriological analysis of water samples collected from all the five sites showed the presence of fecal coliforms making it unfit for drinking purpose. It has been concluded from the above study that the ground water can be used only after suitable treatment.
Key words: Makardhokda, Mines, water quality, fecal coliforms, toxic metals.
