In Sri Lanka owing to the geology, rainfall patterns, land use etc. there is considerable variance in the quality of groundwater. Water quality issues include salinity, hardness, certain minerals such as Fe, Mn, Fluoride, agricultural pollution etc. The required water treatment technology is too expensive for rural water supplies and as a result, often the groundwater source is rejected. The North Central Province, a predominant paddy cultivation area, is plagued with chronic kidney disease (CKD). CKD is present in areas where the groundwater is hard and contains high Fluoride.
