Major Ions Chemistry of Surface Water in Bhindawas Wetland

Abstract

Water samples were taken from different locations in Bhindawas wetland during summer season for analysing major ion chemistry of surface water and its suitability for irrigation and domestic purpose. Along with some major ions, other general water quality parameters like temperature, pH, TDS, EC and Total Hardness were also analysed. Irrigation quality parameters Sodium Absorption Ratio (SAR), Soluble Sodium Percentage (SSP), Residual Sodium Carbonate (RSC), Kelly’s Ratio(KR) were also investigated. The study was carried out in the month of May, 2016. The results showed that majority of samples were suitable for domestic purpose due to low and medium hardness. The values of pH ranges from 6.5 to 7.4, indicating slightly acidic to alkaline nature of surface water. Total dissolved solids ranges from166 to 344 mg/l. All the sampling locations have SAR value and KR value below 10 and 2 respectively, which indicates excellent water quality of lake for irrigation purposes. Also the values of SSP at each sampling locations is below 50 indicating good water for irrigation. Also RSC value for all the samples range below 2.5 and also suitable for irrigation. According to present study it was found that all the parameters were found within the permissible range and suitable for irrigation and domestic purpose.
