Health risk assessment is the largest practice at Sciences, and is at the core of what we do. All of the other practice areas feed into health risk assessment in one way or another. Health risk assessment has been at the core of regulatory decisions in the U.S. for at least 40 years. Dr. Gibb, the President at Sciences, spent over 25 years at the U.S. Environmental Protection Agency, with most of that time at EPA’s National Center for Environmental Assessment where he held positions of Assistant Center Director, Associate Director for Health, and Senior Science Advisor. Other scientists in the company have also played key roles in the development of the science of risk assessment. Some areas we have assisted clients with health risk assessment include:

• Assessment of the risks of environmental substances in all media, including air, water, and soil, and multipathway scenarios.
• Development of methods for improving the accuracy and transparency of health risk assessment.
• Application of health risk assessment to assist decision-makers in the regulation of new and existing chemicals.
