Dr. Douglas has over 35 years of consulting experience in the field of environmental forensic chemistry. He has investigated the nature, extent, fate, source(s) and/or age(s) of contamination in soils, sediments, water and biota at/near active and legacy facilities, urban waterways and marine/riverine oil spills. He has published (60+), presented and testified on the analysis, occurrence, distribution, and fate of persistent chemicals (e.g., PCBs, hydrocarbons, trace metals) in aquatic and terrestrial systems. Dr. Douglas routinely uses chemometric methods to explore complex chemical relationships among contaminated environmental samples and suspected sources and to track the fate of these compounds in contaminated environments. As a former laboratory director, he is highly knowledgeable of environmental laboratory operations and the issues relating to data usability and quality as it relates to forensic investigations. Dr. Douglas routinely provides forensic chemistry support for both industry and government clients on projects ranging from major US oil spills, ports and harbors legacy contamination issues, and soil/groundwater contamination disputes. He has testified in both U.S. and international courts (e.g., United Nations, Business International Tribunals) in support of this work.
