Environmental Damage Assessment

Environmental Damage Assessment and Recovery Planning

Experience conducting environmental injury and damage assessments to characterize the injuries caused by conflict, industrial accidents, and natural disasters using decision support analysis tools such as net environmental benefits analysis (NEBA), comparative risk assessment (CRA), and remedy alternatives analysis (RAA) to advise companies and governments on recovery strategies to restore damaged aquatic and terrestrial ecosystems.

Examples of client assignments include:

  • Review and recommendations to the Ukraine Ministry of Natural Resources and the Environment for improving the Ministry’s seven damage assessment methodologies relevant to quantifying injuries to natural resources after the start of the February 2022 conflict with Russia.
  • A two-year survey of the impacts on the Rio Doce ecosystem and adjacent riparian areas resulting from the November 2015 collapse of the Fundão Tailings Dam in the Brazilian state of Minas Gerais and release of mine tailing waste extending 500 km to the confluence with the South Atlantic Ocean. Collaborating with Brazilian environmental experts and federal prosecutors, the work involved environmental surveys, damage estimation, and cost-benefit analyses of various environmental restoration strategies.
  • A three-year study of baseline coastal and deep-water environmental and ecological conditions in the northern Gulf of Mexico ” the day before” the April 2010 Deepwater Horizon oil spill. Working with project leader, Dr. Calvin (Herb) Ward from Rice University, experts from approximately 25 US Gulf Coast universities and research organizations were retained to examine and quantify, to the extent practical, various coastal, ecological, geochemical, and marine processes along the US Gulf Coast, extending from Florida to Texas.
  • Preparation of a fate and transport model describing the migration of perfluorinated carboxylic acids (PFCAs) from non-specific source areas in the Northern Hemisphere to the Canadian Arctic, including the development of a five-tier Arctic food chain bioaccumulation model to predict PFCA levels at various ecological trophic levels.
