Estimation of water quality of a lake and ground water at masahi village in Haridwar

195-199The uses of groundwater in India has been risen rapidly during the last few decades. This has resulted in depletion of groundwater table in many areas causing concerns for the long term sustainability of groundwater based supplies. The anthropogenic activities cause groundwater pollution in many parts of country. Earlier, Lake in villages serves many purposes viz- drinking, bathing and irrigation etc but now a days lakes are getting polluted. The paper presents the evaluation of water quality of a lake and groundwater in Masahi village, Roorkee, Haridwar, Uttrakhand. The water samples from a lake and groundwater were collected from different location to check the suitability of water for drinking purposes. The water samples were analysed for pH, Turbidity, Electrical Conductivity, Total Dissolved Solids, Alkalinity, Hardness, Sodium, Potassium, Calcium, Magnesium, Bicarbonate, Sulphate, Chloride, Nitrate, Phosphate, Biochemical Oxygen Demand. The results have been compared with the drinking water standard prescribed by Bureau of Indian Standard and it is found that groundwater is suitable for drinking purposes whereas lake water is not suitable for drinking purposes. The result also reveals that lake is highly eutrophic
