Ground water quality is important as it is the main factor determining its suitability for drinking, domestic, agricultural and industrial purposes. The suitability of groundwater for drinking and irrigation has been assessed in patancheru industrial area of medak district of Andra Pradesh, India. In order to assess the ground water quality forty ground water samples were collected in pre-monsoon 2008 and post-monsoon 2008 and analyzed for physical and chemical parameters. Physical and chemical parameters of groundwater such as electrical conductivity, pH, total dissolved solid, Na, K, Ca, Mg, HCO3, Cl, and SO4 were determined. The result shows that the groundwater of the study area is not suitable for drinking purposes and also not suitable for irrigation under ordinary conditions, but may be used occasionally under very special circumstances.
