Spatial interpolation is an important method, getting information about pollutan from landfill location in groundwater quality mapping. Ordinary kriging is used to predict the unknown values in some locations, based on the autocorrelations among the nearby locations. In this research, ordinary kriging interpolation was used to divine the chemical characteristic of Manganese (Mn) and Lead (Pb), then 22 samples, around the Integrated Waste Management (TPST) Bantar Gebang, were taken for the purpose. In conclusion, there is an autocorrelation spatial among those locations. In addition, the Gaussian variogram model gives a better result than the Exponential model and the higher of Mn and Pb is in the southeast of TPST Bantar Gebang. This location has the high chance to be an affected pollution area.
