Abstract :

As groundwater is a vital source of water for domestic and agricultural activities in Southeastern part of Ranga Reddy district due to lack of surface water resources groundwater quality and its suitability for drinking and agriculture usage were evaluated. Physical and chemical parameters of groundwater such as pH, Electrical Conductivity, Total Dissolved Solids (TDS), TH, Na+, K+, Ca2+, Mg2+, Cl–, HCO3–, CO3–, and, SO4– and Chemical index like Percentage of Sodium (%Na), Chloro Alkaline Indices (CAI), Kelley’s Ratio, Gibb’s and Magnesium hazard were calculated based on the analytical results. The chemical relationships in Piper diagram identify Ca–Na–HCO3 and mixed Ca–Na–Mg–HCO3 as most prevent water types. Alkaline earths exceed alkalies and strong acids exceed weak acids. High total hardness and TDS in a few places identify the unsuitability of groundwater for drinking and irrigation. Such areas require special care to provide adequate drainage and introduce alternative salt tolerance cropping.
