Online published on 29 January, 2021. Abstract The present work aims at investigating the groundwater chemistry in Lakavarapu Kota region of Vizianagaram district by analyzing the groundwater samples collected from several sampling locations spread across the study area uniformly. 360 groundwater samples, 120 samples each in Post-monsoon (November 2018-February 2019), Pre-monsoon (March 2019-June 2019) and Monsoon (July2019-October 2019) are collected from bore holes of 30 selected locations in the study area at regular monthly intervals and analyzed for various quality indicating parameters such as pH, EC, TDS, TH, TA, Ca2+, Mg2+, Na+, CO32-, HCO3-, Cl-, SO42-, NO3-, F- using standard laboratory procedures. Canadian Council of Ministers of the Environment Water Quality Index (CCME-WQI) method was used to assess the overall quality of groundwater in the study area. It is observed that quality of about 16.67% of the water samples is Excellent, about 43.33% is good, about 20% is fair, about 16.67% is Marginal and remaining 3.33% is poor for drinking purpose in the study area.
