A risk assessment that re-evaluated receptors and exposures due to a change in property use from commercial to recreational over the course of the project.

Assisting state agencies in the development of screening values under a variety of regulatory programs.

Ongoing risk evaluations of “hot spots” at a large bulk chemical storage facility.

Conceptual model and statistical analysis to demonstrate attainment of the background standard.

A residual risk assessment performed to account for an unstable groundwater plume, including development of a post-remedial care plan.

Conservative vapor intrusion modeling scenarios performed for off-site residence with limited knowledge of subsurface conditions.

A toxicity assessment of noncarcinogenic effects on target organs for a construction and utility worker in the adjacent right-of-way.

Risk assessment for a former automotive service station with a radial groundwater flow pattern surrounded by residential properties.

A risk assessment excluding arsenic as a constituent of interest through a multiple lines of evidence approach supporting that arsenic is a naturally-occurring constituent.

A quantitative risk assessment evaluating a construction/utility worker in a long stretch of right-of-way by segmenting the datasets and exposure parameters to reduce need for extensive mitigation.

A risk assessment prepared for a petroleum refinery and chemical storage terminal located outside of the United States.

A risk assessment evaluating preferential and diffuse flow groundwater migration and subsequent discharge to an adjacent stream. Surface water exposures to a recreational user in the stream were evaluated.
