The presente work evaluates the use of geostatistical method (stochastic) as evaluator of the efficiency of the ISCO remediation systems in a geologically heterogeneous area contaminated by DNAPL. For the study was chosen an area of Cubatão city, because there is a strong heterogeneity there, which creates uncertainties towards the remediation method. Also because it is a chemical and petrochemical pole, considering a hypothetical contamination in the area, next to Cubatão river. In the area were discriminated 5 lithologies and attributed different hydraulic conductivity values: clay, silt, debris flow, impure sand and pure sand. With the purpose of reducing the uncertainties, stochastic simulations were performed using SGeMS software, based on drilling wells information, obtaining 9 different and equiprobable scenarios. Whith the stochastic simulation result flow simulations were performed using the software MODFLOW and transport also, performed using the software MT3DMS, it was possible to verify a low efficiency of the ISCO remediation method, reaching in average 41,4% of the contaminated area. In general it provides a broad view of the possibilities, the use of the stochastic method for the evaluation of ISCO remediation methods can be evaluated positively
