Hydrogeochemical Assessment of Groundwater

Groundwater constitutes an important source of water for drinking, agriculture and industrial production. The use of groundwater has increased significantly in the last decades due to its widespread occurrence and overall good quality. Water quality index exhibits the overall water quality at a specific location and specific time based on several water quality parameters. The objective of an index is to turn complex quality data in to information that is understandable and usable by the public. The water quality of the Kadapa town varied from excellent to good. The high value of WQI at these stations has been found to be mainly from values of fluoride, Electrical conductivity. In some of the collected samples, the concentrations of these parameters exceed the permissible limits of WHO and ISI standards. After evaluating the data of this study it is concluded that there is an instant need to take ameliorative steps in Kadapa, Badvel, Kalasapadu, Porumamilla mandals, Vemula, Vempalli of Y.S.R District to prevent the population from groundwater pollution. Measures on a groundwater-quality monitoring program are suggested for the sustainable development of this area.
