Potability of groundwater in kotturu mandal of Srikakulam district, Andhra Pradesh has been investigated and presented in the present paper. For this purpose, the water quality index (WQI) method has been adopted. Various physic-chemical parameters such as electrical conductivity, pH, turbidity, total dissolved solids, calcium (II), magnesium (II), fluoride, chloride, dissolved oxygen, total alkalinity, and nitrite were experimentally determined to compute WQI. The results obtained for the physic-chemical parameters have been compared with the BIS standards. The results of WQI computation infer that the groundwater of the two mandal is rated as “good” for human consumption. Correlation between various parameters has also been computed and the results were presented.
