History

The Potomac Section is a local section of the American Industrial Hygiene Association (AIHA). We serve the Washington, D.C. metropolitan area, including the adjacent Maryland and Virginia counties, but are all welcome to join!

This Potomac Section website serves to keep members, colleagues, community, and AIHA National informed of its many activities. The section provides its members continuing education and networking opportunities through monthly section meetings from September through June. In addition, the section sponsors professional development meetings - with the Smithsonian and Conservation Groups in the Fall and a general meeting in early spring. We also sponsor awards and provide judges for local middle school and high school science fairs.
