Quality of Tube Well and Open Well Water from Ausa Tahsil of Latur District

The study was carried out in Ausa tahsil of Latur district to estimate the quality of groundwater for agricultural purposes. Total 100 water sample was collected from tube well and open well in different location and analyzed for pH, EC, cations (Ca²⁺, Mg²⁺, Na⁺ and K⁺) and anions (CO₃^2-, HCO₃^- and Cl^-) to assess the irrigation water quality with sodium adsorption ration (SAR) and residual sodium carbonate (RSC). From the computation of SAR and RSC values, 100 percent groundwater samples were suitable. USSL diagrams show that the samples are safe for irrigation usage. Considering overall results, the concentration of EC, cations (Na⁺, Ca²⁺ and Mg²⁺) and anions (HCO₃^- and Cl^-) in tube well were higher as compare to open well water. Thus, can concludd that open well water is suitable for irrigation as compare to tube well water for irrigation.
