Groundwater provides an overview of environmental conditions in an area. Chemical analysis of groundwater will provide information about the origin and quality of groundwater as a basis for groundwater utilization. In this paper, analysis is carried out by determining the water types of unconfined groundwater. Unconfined groundwater sample were taken from Southern Bandung. Measurement of major ion (sodium, potassium, magnesium, calsium, chloride, sulfate and bicarbonate), also pH and electrical conductivity were carried out in 16 groundwater samples. Paper discusses a) the classification of groundwater types determined by Kurlov method, b) the correlation of chemical properties in groundwater determined by Stiff method. Result showed that unconfined groundwater in Southern Bandung was dominated by calcium cations and bicarbonate anions, and water type were dominated by calcium – alkali – bicarbonate – chloride. Correlation of chemical properties in groundwater is seen in several location which show groundwater in the same flow and is fresh.
