Groundwater is an important and valuable source for irrigation, drinking and power sources. The main objective of this paper is to evaluate water quality index of groundwater in and around Lakkireddipalli and Ramapuram by using Water Quality Index (WQI) method. In the present study, a detailed investigation was carried out with an objective of identifying the groundwater quality, prominent water quality parameters controlling the hydrochemical evolution of aquifer system was studied. Water quality index was applied in present study area by using ten water quality parameters like pH, Electrical conductivity (EC), Total dissolved solids (TDS), Total Hardness (TH), Total Alkalinity (TA), calcium (Ca2+), magnesium (Mg2+), chloride (Cl-) sulfate(SO42-) ,and fluoride (F-). According to water quality index classification 70% of samples fall in class B: good category and 23% of samples fall in class C: poor water quality and only 7% of samples fall in class A: excellent water quality.
