Teck American Incorporated, with the oversight and approval of EPA, has assembled an experienced team of environmental scientists and engineers who will conduct studies of the Upper Columbia River. These experts are responsible for completing the expanded studies. They will design and implement field sampling and analytical programs that will help them evaluate the nature and extent of contamination, determine the presence of unacceptable risks and decide what actions may be necessary to alleviate the risks. Combined, the technical team of experts and professionals has over 150 years of experience in these kinds of studies and assessing risks associated with potential contaminants to human health and the environment.

Some of the key individuals are introduced below; however, they are part of a large team of qualified people dedicated to completing this project.


Dr. Jennifer Holder

Partner and global leader of sediment and watershed services at ERM, Dr. Holder’s practice focuses on assessing contaminated sediment sites throughout the U.S. and globally. Her experience evaluating the impacts of stressors on the environment has resulted in her key role in directing, managing and conducting risk assessments at contaminated sites, addressing clean water act issues, and determining injuries for natural resource damage assessments.

Dr. Doug MacNair

Dr. MacNair focuses on helping his client’s value environmental and natural resource services in their decision making using quantitative economic and business tools. These tools have been used in a wide variety of settings including human-health risk assessments.  Dr. MacNair has extensive experience in natural resource economics. He has developed comprehensive cost-benefit analyses about recreational benefits such as fishing, hiking, and hunting and the economic health effects of air pollution. He has managed numerous recreation surveys of the public, conducted focus groups, and conducted stakeholder meetings.
