Internet Geographical Exposure Modeling System (IGEMS)

April 2011 - Vol. 30

Federal vs. State: Federal

Description: The Internet Geographical Exposure Modeling System (IGEMS), currently under development, is a modernization of several older stand-alone models. IGEMS brings together in one system several EPA environmental fate and transport models and some of the environmental data needed to run them. It also uses graphing and Geographic Information System (GIS) capabilities. IGEMS will eventually include models and data for ambient air, surface water, soil and ground water. Interactive menus guide users through selecting models, selecting and organizing data to be used as input to model runs, executing model runs, presenting model outputs, and accessing user help. With the IGEMS graphical and GIS capabilities, users can view the results as isopleths, vectors, etc., and as geographic presentations, including overlays with population and geographic location. The beta test version of IGEMS is available online now; the final release date will be determined after peer review.
