The present study deals with the classification of deep ground water by using various graphical representation in the lower alluvial plains of Narmada valley between Khalghat and Harinphal, M.P. In the present work, fifteen representative deep ground water samples were collected during premonsoon and postmonsoon period. The collected water samples were analysed with the help of standard methods proposed by APHA (1985). A variety of graphical representation methods like Colin's bar diagram, Trilinear diagram, Modified Trilinear diagram and Wilcox diagram have been used to classify the deep ground water into various geochemical facies. Plottings in various diagrams reveals that majority of the deep groundwater belongs to Calcium bicarbonate type without having any bicarbonate hazard
