The present study deals with the physicochemical parameters of seasonal fluctuations of Groundwater quality analysis in Gulbarga district, Karnataka, India Research findings for fluoride asses in drinking water reveals that in the period of 2015 to 2016 most of all the samples were found to be exceeded the WHO 1995 drinking water standards it effects on the Human health It is said that water was found on Earth approximately 3 billion years ago. Groundwater quality is an important issue to assure from its safe and stable use. However, describing quality conditions is generally difficult considering the spatial variability of pollutants and a wide range of indicators (biological, physical and chemical substances) which can be measured. In this research, groundwater quality of Gulbarga District, Karnataka located in southern part of India. I have been selected to 35 study sites and analyzed the quality of water. A groundwater threat is now posed by an ever-increasing number of soluble chemicals from urban and industrial activities and from modern agricultural practices. Nevertheless, landslides, fires and other surface processes that increase or decrease infiltration or that expose rock and soil surfaces interacting with downward-moving surface water, may also affect the quality of shallow groundwater.
