Models, Databases and Tools for Land and Waste Management

To assess the potential risk from contaminated sediments and to help determine contamination levels for remedial designs, several ecological risk assessment tools are available.

• Exposure Research Tools and Databases for Land and Waste Management
• Sediment Accumulation Factor Data Set: evaluates the transfer of chemicals from sediments into the aquatic food chain
• PCB Residue Effects Database: used for risk assessment of polychlorinated biphenyls (PCBs) and other dioxin-like compound residues with toxic effects
• ECOTOX Database: provides ready access to single-chemical toxicity information for aquatic and terrestrial life
• Center for Subsurface Modeling Support: provides public domain ground water and vadose zone modeling software, services, and technical assistance
• Modeling Subsurface Petroleum Hydrocarbon Transport: OnSite set of tools to assess the impacts from ground water contaminants
• Center for Exposure Assessment Modeling (CEAM): provides predictive exposure assessment techniques for aquatic, terrestrial and multimedia pathways for organic chemicals and metals
