SEDIG exists to serve as a scientific resource to all stakeholders interested in the topic of sediments in the environment, and fulfills the following mission and purpose:

  • Serve as a focal point within SETAC as a means of involving the membership in research and discussions.
  • Stimulate critical assessment in order to establish the best available science.
  • Encourage the worldwide incorporation of the best available science and strategic approaches.
  • Advance overall understanding of the fate, effects, and potential environmental consequences of contaminated, altered or redistributed sediments.
  • Provide scientific support to facilitate effective regulatory decision making.
  • Provide a neutral forum and focal point for collaborative identification, evaluation, and resolution of scientific issues.
  • Provide a forum for organizing sessions at annual meetings and organizing workshops to address scientific issues associated with the assessment and management of contaminated sediments.
  • Provide a mechanism to publish journal articles and books associated with the assessment and management of sediments.


The scope of SEDIG comprises environmental aspects of quantity and quality of sediments, both as deposits and as suspended matter in freshwater, estuarine and marine environments. Scientific coverage of SEDIG includes all fields pertinent to conducting effective environmental risk assessment and management of sediment, including issues such as transport, fate, exposure, effect, impact analysis, guideline values and frameworks (regulations), and management strategies. Where necessary, the adjoining compartments like soil, water, groundwater, air will be considered and contacts with advisory groups like the established SETAC Soil Interest Group will be established. SEDIG, through its broad membership, will aim for cooperation and exchange with international sediment-related organizations such as the European Sediment Network "SedNet,” the Sediment Management Work Group, the Sediment Remediation Technology Development Forum, providing a strong link to application.

Working Groups

A series of working groups exist within SEDIG that seek to engage members with common interests.   Four of the currently active working groups are listed below  with contact details.  Further details of the working group aims are provided on the SETAC web site.

  1. Harmonization of methods for assessing contaminated sediments.  Chair: Teresa Norberg-King
  2. Risk Management Working Group.  Chair: Tamara Sorell
  3. Compilation of contaminant-spiked sediment toxicity data (SETAC database).  Chair: Steven Bay
