    Saline intrusion has been a major source of groundwater contaminant in coastal regions. The situation has adversely affected groundwater quality . Being an essential source of freshwater for the teeming population over the world and indeed Nigeria and its suitability for various uses is largely dependent on physico-chemical quality, this study therefore selected for its quality assessment, the coastal aquifer of Buguma in rivers state Nigeria. Water samples collected from various locations using systematic random sampling were subjected to physico-chemical analysis . sodium (Na2+) (288mg/l) chloride(Cl-)(414.7mg/l) and nitrate (N03-)(64.45 mg/l) ions dominated the major ions of sample results and also exceeded the Nigerian Standard for Drinking Water Quality NSDWQ 2007 and WHO drinking water standard 2006. Among the trace elements, Fe2+ and As ions were above the drinking water regulatory limits of NSDWQ and WHO. Classification techniques were employed to provide an assessable information on the chemical composition of the water samples like the major ions in the analysis. The high proportion ofNa2+, K+ and Cl-as typified by the graphs classified the water as Na K, Cl- type which confirmed saltwater intrusion. The water therefore needs adequate treatment to raise it to portable standard.
