REPRESENTATIONS OF GROUNDWATER PHYSIOCHEMICAL CHARACTERISTICS NEAR THE SUBURB AREA OF ASAN RIVER (UTTARAKHAND), INDIA

Water, as an excellent solvent, dissolves minerals in the geological system. Several factors, such as chemical weathering of the rocks, influence the physicochemical nature of groundwater. Because of the presence of contamination in groundwater, people living in metropolitan cities are more likely to suffer from certain health problems. The current study was carried out to examine the various groundwater parameters in five suburban area of Asan River (Chandrabani, Badowala, NayagoanMallan, Parval Village and Herbertpur) Dehradun, and to check its fitness for drinking. Eight water quality variables/parameter (pH, TDS, Alkalinity, Total Hardness, Calcium Hardness, Magnesium Hardness, Chloride, Nitrate) were selected for this analysis. Twenty samples of groundwater were collected from the five sampling sites by using 1 litre sterile polyethylene bottles during a period of six months. The pH and TDS were estimated by Digital soil and water analysis kit, alkalinity, chloride, total hardness (Ca &Mg) was determined by titration methods. The formula was used to calculate the total suspended solid. The concentration of nitrate in ground water samples was determined using a spectrophotometer. The results of the analysis were compared to the BIS standards for drinking water (IS 10500:1991). Further, the groundwater was classified on the basis of Freez and Cherry [1], Sawyer and Mccarty [2] and Stuyfzand's Classification.
