North American Metals Council – Selenium Working Group (NAMC-SWG) 

Overview

The Selenium Working Group of the North American Metals Council (NAMC-SWG) comprises professionals from industry and consulting engaged in sharing and commissioning technical research on issues pertaining to ecological and human health effects, regulation, and water treatment of selenium in the context of industrial discharges.

Activities include:

  • Support of research to inform the development of water quality and biological tissue-based standards/guidelines for selenium;

  • Implementation and application of standards/guidelines (e.g., sampling and analysis techniques and technologies);

  • Development of effects thresholds;

  • Identification of analytical methods pertinent to such standards/guidelines; and

  • Review of technologies for the treatment of selenium in waste waters.

As part of its ongoing efforts, the NAMC-SWG develops white papers and peer-reviewed journal articles on these topics for public sharing. In addition, the NAMC-SWG provides scientific/technical input when there are opportunities to comment on revisions to various North American regulations regarding selenium in the context of environmental protection (see below).

The NAMC-SWG meets biannually in the United States (associated with the North American meeting of the Society of Environmental Toxicology and Chemistry (SETAC)) and once mid-year in Canada.

Membership

Membership in the NAMC-SWG is open to companies that have a need and an interest in managing, regulating, monitoring, or treating water for potential effects/impacts of selenium; this includes associations representing such companies. Consulting firms and water treatment suppliers may join the NAMC-SWG as Consultant Members. The group occasionally invites academic and government scientists to its meetings, to present new research and to update the group on relevant regulatory developments.
