N2 - Potable water draws attention of human being due to scarcity of clean water. Contamination of surface, subsurface and groundwater has thus become a serious problem in nationwide. Hence, the assessment of water quality is utmost important to preserve and restore the surface, subsurface and deep-water sources. The main intent of this paper is to present of the groundwater quality status for future planning and management of Wanathawilluwa aquifer in Puttalam district. The assessment of the water quality was carried out in the different locations at Wanathawilluwa. Physiochemical analysis was carried out for surface, subsurface and deep aquifer water samples to provide a single number for Water Quality Index (WQI) that expresses the overall water quality of corresponding water at certain location. WQI was calculated using the weighted arithmetic index based on several water quality parameters such as pH, Total Dissolved Solids, Phosphate, Nitrate, Turbidity, Electrical Conductivity, Dissolved Oxygen and Chemical Oxygen Demand. By representing the whole Wanathawilluwa aquifer, 21 deep and subsurface water samples from different locations were tested and results were compared with stipulated Sri Lanka Standards for potable water. The estimated WQI of Wanathawilluwa aquifer reveals that the overall water quality class is ‘good’ and water is acceptable for domestic use.
