    Assessment Of Water Quality Index For Groundwater Of Valsad District Of South Gujarat (india)
    (University of Eloued جامعة الوادي, 2013-07-01) Shroff, P.; Vashi, R. T.
    The present study aims the assessment of the water quality index (WQI) for the groundwater of Valsad district of South Gujarat. Total fifteen sampling stations from five talukas of Valsad district were selected and groundwater samples were collected for two years (from August 2007 to July 2009). In this present study, WQI created by Canadian Council of Minister of the Environment (CCME) was used. For calculating the WQI, groundwater samples were analyzed for seventeen physico-chemical parameters like pH, Colour, Electrical Conductivity (EC), Total Hardness (TH), Calcium (Ca), Magnesium (Mg), Total Alkalinity (TA), Total Dissolved Solids (TDS), Silica, Chloride, Sulphate, Fluoride, Sodium, Chemical Oxygen Demand (COD) and metals like Copper (Cu), Lead (Pb) and Manganese (Mn). The WQI for Valsad district suggests that the groundwater quality is marginal.

    Correlation Study Among Water Quality Parameters Of Groundwater Of Valsad District Of South Gujarat (india)
    (University of Eloued جامعة الوادي, 2015-09-01) Shroff, P.; Vashi, R. T.; Champaneri, V. A.; Patel, K. K.
    Groundwater samples were collected from five talukas of Valsad district for one year (from August 2008 to July 2009) and were analyzed for their physicochemical characteristics. The present investigation is focused on determination of parameters like pH, Colour, Electrical Conductivity (EC), Total Hardness (TH), Calcium (Ca), Magnesium (Mg), Total Alkalinity (TA), Total Dissolved Solids (TDS), Silica, Chloride, Sulphate, Fluoride, Sodium, Chemical Oxygen Demand (COD) and metals like Copper (Cu) and Manganese (Mn). Correlation coefficients were determined to identify the highly correlated parameters and interrelated water quality parameters. Correlation matrix of Valsad district suggests that EC of groundwater is found to be significantly correlated with eight out of seventeen water quality parameters studied. It may be suggested that the quality of Valsad district can be checked very effectively by controlling EC of water.

    Seasonal Variations In Groundwater Quality Of Valsad District Of South Gujarat (india)
    (University of Eloued جامعة الوادي, 2015-05-01) Shroff, P.; T.vashi, R.
    Groundwater is an important precious natural resource. For optimum utilization of water resources, it is necessary to know both the quality as well as quantity of water. The present investigation is focused on seasonal variation in groundwater quality of Valsad district of south Gujarat (India). Groundwater samples from fifteen sampling stations were collected for two year i.e. from Aug 2007 to July 2009 and analyzed for pH, Colour, Total Hardness (TH), Calcium (Ca), Magnesium (Mg), Total Alkalinity (TA), Chloride and Sodium. Marginally higher level was observed in almost all parameters in summer season. No significant change observed in pH, Colour and Calcium.
