Internet Geographical Exposure Modeling System (IGEMS)
Entry ID: EPA-IGEMS


Summary
Abstract: The new IGEMS is a modernization of OPPT's older Graphical Exposure Modeling
System and PCGEMS tools. IGEMS brings together in one system several EPA
environmental fate and transport models and some of the environmental data
needed to run them. IGEMS includes models and data for ambient air, surface
water, soil, and ground water, and makes the models much easier to use than
their stand-alone counterparts. IGEMS will have graphics and Geographical
Information System (GIS) capabilities for displaying environmental modeling
results.

How Does IGEMS Work?

The new IGEMS will have interactive menus to guide the user in selecting
models, selecting and organizing data to be used as input to model runs,
executing model runs, and presenting model outputs. The menus will also provide
user help. The new system will be modular in design, so that EPA can easily add
other models to the system in the future. IGEMS will also have the capability
of retrieving some data from EPA Oracle databases, such as the TRIS data in the
EPA Envirofacts Data Warehouse.

Use Constraints
To run IGEMS successfully, we strongly recommend a Pentium PC 500 M Hertz or
above with a minimum of 256 M memory (RAM). Please close all other unnecessary
programs to free up more memory for your PC. We also strongly recommend a fast
Internet connection, such as a cable modem, DSL, or T1 line and a Netscape or
Microsoft Internet Explorer web browser are needed to use the Internet version
of IGEMS.
