A. Dallas Wait, Ph.D.
Dr. Wait is a chemistry expert with over 30 years of experience characterizing consumer products, evaluating the source and fate of chemicals in the environment, designing test method and quality assurance programs, interpreting data, and determining the validity and usability of chemistry measurements and sampling procedures. Dr. Wait's consultations often resolve data quality issues, aid in agency negotiations concerning data usability, and provide pivotal chemistry testimony. More recently, his practice has expanded into the dietary supplement industry, resolving product adulteration and testing reliability issues. He is on the editorial board for three peer-reviewed journals and coauthored the second edition of US EPA's SW 846 RCRA Test Method Manual. Dr. Wait is a member of numerous scientific work groups and science advisory boards involved in developing and evaluating test methods and quality assurance programs, such as ASTM, the Methods and Data Comparability Board, and the AOAC Presidential Task Force for Dietary Supplements. Before joining Gradient in 1989, he was Technical Director, Vice President, and cofounder of ENSECO's ERCO Laboratory, a nationally prominent environmental laboratory involved, in part, with oil spill research, agency method development studies, aquatic toxicology GLP testing support, consumer product analysis, and site investigations.
