Risk Assessment

• SV conducts the four parts of a Human Health Risk Assessment, which are Data Assessment;        Exposure Assessment; Toxicity Assessment; and Risk Characterization.

• Site-specific risk assessments:  Deterministic, probabilistic, Monte Carlo simulation

• Complex risk assessment techniques:  probabilistic analysis; physiologically based pharmacokinetic (PBPK) modeling; development of cancer slope factors, reference doses/concentrations, Benchmark Dose Modeling

• Geochemical analysis

• Fingerprint analysis

• Advanced statistical and epidemiological models

• Chemical fate and transport

• Sampling plans

• Base realignment and closure (BRAC) and Brownfields sites

• Mitigation and remediation plans

• Indoor air vapor intrusion:  calculation of cancer and noncancer risks for all chemicals identified in     groundwater, hydrogeological, and sub-slab data

• Technical review, analysis, and revision of preexisting risk assessments

• Inorganics, volatile organic compounds, radionuclides, asbestos and asbestos-like fibers, dioxins, PCBs, etc.

• Multiple receptors and pathways

• Training programs and courses

• Complex mining sites, chemicals, petroleum, radiation

• Residential property cleanup levels

• Evaluation of land use projects for contaminated properties (BRAC and Brownfields)

• RCRA, CERCLA, UST

Litigation Support and Expert Witness Testimony

• Pretrial legal and negotiation support on issues involving toxicology, chemical fate and transport, risk assessment and risk management, and environmental laws and regulations

• Expert reports and rebuttals

• Expert witness testimony

• Extensive public speaking and university teaching experience

Negotiation Support

• SV staff have served as lead negotiators in over 150 regulatory meetings, providing expert toxicological, risk assessment, and risk management support

• Public meetings

• Pretrial legal and negotiation support on issues involving toxicology, chemical fate and transport, risk assessment and risk management, and environmental laws and regulations

White Papers and Policy

• Stormwater harvesting and reuse policies for state and local governments

• EPA:  Technical oversight for Draft Human Health Risk Assessment Protocols for Hazardous Waste Combustion Facilities and Screening Level Ecological Risk Assessment Protocols for Hazardous Waste Combustion Facilities

• EPA:  Technical lead for EPA Region VI in developing a new technical guidance document for RCRA sites, Risk Management Strategy

• EPA:  Compiled a database for conducting Monte Carlo simulations and provided technical review on supplemental guidance for conducting Monte Carlo simulations for EPA Region VIII.  Developed a cost-effective risk assessment template for RFP to streamline and provide consistency for all risk assessments.

• Department of Defense:  Comprehensive guidance document on sampling and analysis, and conducting risk assessments at PCB- and dioxin-contaminated sites for DOD.  These documents were used to train Navy personnel in the environmental restoration program who are responsible for remediating Navy installations that will be returned to civilian use.

• Department of Defense:  Conducted a background analysis implementing Procedural Guidance for Statistically Analyzing Environmental Background Data, which he authored for the Navy, at NAS Whiting (Milton Florida).  This approach is being used to identify chemicals of concern for risk assessment, evaluate Applicable or Relevant and Appropriate Requirements (ARAR), and identify chemical releases.  Successful completion of this project is expected to save DOD and the state of Florida $30 million in potential remediation costs.

• Department of Defense:  Conducted risk assessments for NAS Alameda in California.  Responsible for developing the overall risk assessment approach and negotiating all technical aspects of the Navy project with local, state, and federal regulators.  Tasked with preparing innovative approaches to establish anthropogenic and nonanthropogenic background conditions, preliminary remediation goals, and data aggregation to estimate exposure-point chemical doses.  Responsible for developing a Navy policy document for risk-based corrective action (RBCA) at petroleum sites.

• Massachusetts Department of Environmental Protection:  Provided technical expertise to the Massachusetts Department of Environmental Protection for radionuclide risk assessments, compliance, and cleanup standards.  Worked with the state to develop state guidance for radionuclide cleanup of all Department of Defense and Nuclear Regulatory Commission operated sites within the state.
