This work was initiated to investigate current situation and problems in applying groundwater-related models for various kinds of environmental impact assessment in Korea. and therefore. to enhance appropriate application in the future. This study was carried out with 544 and 16 documents of EIA (Environmental Impact Assessment. Law of Environmental Impact Assessment) and Mineral-Water EIA (“the environmental impact investigation for mineral water developments”; Law of Drinking Water Management). respectively. It was revealed that there were considerably many cases which may cause serious impacts on subsurface environments in EIA. However. none applied groundwater models. Generally, the influences on subsurface system were underestimated or even ignored in EIA. For Mineral-Water EIA. groundwater models wert applied. in general. But. numerous and serious problems were noted: limited number of calibration parameters and parameter types. setting boundary conditions without adequate bases. recharge rates several times higher than precipitation rates. numerically unstable results. etc. Such kinds of misusages seem to be caused by modelers larking in professional knowledges. To solve the problems revealed from this study. more systematic re-education programs are suggested.
