Abstract :

In order to assess the groundwater suitability for drinking and irrigation purposes in parts of Kothur area, Mahabubnagar district, Andhra Pradesh. 50 groundwater samples were collected and analyzed for various parameters. The various parameters were evaluated such as pH, Electrical Conductivity (EC), Total Dissolved Solids (TDS), Total Hardness (TH), Na+, K+, Ca2+, Mg2+, Cl–, HCO3–, CO3–, SO4–, NO3– and Chemical index like Sodium Adsorption Ratio (SAR), Sodium Percentage (% Na) Residual Sodium Carbonate (RSC), Magnesium Hazard (MH) and Kelly Ratio (KI) were calculated based on the analytical results. Based on US salinity diagram, 80% of the groundwater samples fall in the C2–S1 water class, indicating medium salinity and low sodium waters. The abundance of the major ions is as follows: CO3 > NO3 > Cl and K > Mg > Ca. These parameters were compared with standard limits and were found to be in limits and suitable for irrigation purpose.
