Methods are needed to allow regulatory agencies and resource managers to predict, from readily available data, the potential for groundwater contamination problems. Regional maps developed from these methods can aid in planning and allocation of resources. The literature was searched for methods capable of filling this need. Six methods were selected and compared using hypothetical hydrogeologic settings. Based on the results obtained, which varied considerably between methods, none of the methods is completely satisfactory. Of the reviewed methods, 'DRASTIC' seemed to be most suitable.
