Toxic-Risk LLC supports technically demanding projects with sound science, practical judgment, and a candid understanding of what clients need in order to move forward with confidence.
01
Work includes originating Reference Value Arrays to help risk assessors identify the most suitable human health reference values, initiating an agency-wide strategy for managing and communicating environmental health science information using semantic matching and ontologies, and leading development of an acute reference concentration methodology later published by the OECD.
02
Dr. Woodall served on the National Advisory Committee for Acute Exposure Guideline Levels (AEGLs (opens in a new tab)) from 2004 to 2015 and was primary author on several AEGL documents. He was also called upon to provide support following several accidental releases of toxic chemicals to the environment (e.g., Deepwater Horizon and the East Palestine train derailment).

Service on EPA regulatory work groups included scientific support for air quality regulations covering Hazardous Air Pollutants (HAPs (opens in a new tab)) as required under the Clean Air Act, and review of risk evaluations and proposed rules under the Toxic Substances Control Act (TSCA (opens in a new tab)). Dr. Woodall also led the multi-agency Air Sensors Health Group, organized major workshops and symposia, and while at API commented on pending regulations using arguments grounded in sound science.

Professional training covers the basics of toxicological sciences and the practice of risk assessment, with deeper instruction shaped around participants' needs. Contact Toxic-Risk to discuss the scope and goals of training for your organization.
Core Principles
These principles shape what work Toxic-Risk accepts, how that work is carried out, and how clients are advised when the science, scope, or expectations need to be addressed directly.
This commitment has been the common theme across George Woodall's entire career and was fully tempered during 23 years with the U.S. EPA. Toxic-Risk will not abandon this principle under any circumstances.
Toxic-Risk will work diligently in the best interests of clients, but never by compromising ethical integrity, core principles, or the integrity of any client organization.
Potential clients receive a candid assessment of Toxic-Risk's abilities, and projects are declined when the client's needs cannot be fully met. Before any agreement is signed, the request, scope, expectations, and intended final product are reviewed to ensure full understanding on both sides.
