Risk Assessment

The risk of adverse effects to human health or ecological receptors is the primary driver at most environmental sites. The tools presented on this page include:
Models that are used to evaluate a specific pathway
Graphically based tools that provide a geospatial basis to calculate exposure point concentrations
Comprehensive packages that provide a collection of models and databases, that the user may link together based on their conceptual site model (CSM).

1 ERPIMS data can be imported through an Access file or a series of text files (.tes, .res, .sam, .ldi).
2 GeoSEM uses several GIS vector and raster file formats: DOD vector product format (VPF) , ESRI product files, CAD drawings (dxf), ASCI II grids, and georeferenced image formats such as geoTIFs, bitmaps, GIFs, JPGs, and ERDAS.
