human health risk assessment

We have a team of health professionals, modelers, and statisticians to support human health risk assessment. We apply appropriate risk assessment tools to support all phases of environmental decision making, including

• calculation of site-specific risk-based screening values and extensive experience in performing screening level risk assessments,
• performance of human health risk assessments consistent with applicable regulatory guidance,
• use of simple bounding analyses with average and maximum exposure or probabilistic risk calculations to support risk management decisions and cost-benefit analyses,
• analysis of relative risk associated with remedial decision alternatives,
• application of a toolbox of contaminant transport models (e.g., Multimed, MEPAS, HELP, RESRAD, MODFLOW, ArcInfo GRID, HSSM, USGS MOC) to support the analysis of future risk scenarios, and
• development of project-specific contaminant transport and risk models to support risk management decisions at complex sites.

We have also developed human health risk assessment training.

Example projects include the following.
