Groundwater is part of an important resource for the majority people however, shallow groundwater vulnerable to contamination. The aim of this study is to determine areas of vulnerability of shallow groundwater and analyze the spatial pattern of shallow groundwater vulnerability to contamination with SINTACS and SINTACS-Lu in Taman Rahayu. Hydrogeological data that is used are the depth of shallow groundwater (S), net recharge (I), unsaturated zone condition (N), soil texture (T), aquifer media (A), hydraulic conductivity (C), slope (S) and land use (Lu). The Groundwater vulnerability level is calculated by summing the rating values after multiplied by the weight value of each parameter to produce value called SINTACS index. Data analysis was performed using Geographic Information Systems (ArcGIS 10.3) and from overlay of each parameter that produces vulnerability level maps of groundwater. Both models vulnerability verification by measuring the concentration of nitrate in the areas of vulnerability. The result showed that the areas of vulnerability of shallow groundwater models divided into three classes, low, medium and high vulneranility level. Cross table test showed an accuracy 70% for SINTACS and 80% for SINTACS-Lu model.
