Assessment of Groundwater Quality for Irrigation Purpose in Manapparai Block, Tiruchirapalli District, Tamilnadu
Journal Title: International Journal of Agricultural Science and Research (IJASR) - Year 2017, Vol 7, Issue 5
Abstract
Groundwater quality assessment is an important factor, to determine the suitability of water for irrigation use. Twenty-five groundwater samples were collected and calculated the various parameters, such as pH, EC, Cations (Calcium, Magnesium, Sodium and Potassium) and Anions (Chloride, Sulphate, Carbonate and Bicarbonate), using standard methods. The results of the concentrations were analysed with different irrigation indexes like EC, sodium percentage (SP), Sodium Adsorption ratio (SAR), Residual Sodium Carbonate (RSC), Permeability Index (PI) Magnesium Hazard Ratio (MH) and Kelly’s Ratio (KR). Majority of index results such as SP, SAR, RSC, PI, MH and KR implying that, the 80 percent of the groundwater samples fall under excellent to good category and remaining 20 percent samples fall under poor condition. But, only based on EC, 80% of the samples fall under the high salinity category. Hence, the results were concluded that, the groundwater quality in the study area was suitable for irrigation purpose.
