The Potomac Section is one of two local sections of the American Industrial Hygiene Association (AIHA) in the nearby vicinity of the Association's National Headquarters in Fairfax, Virginia: the Potomac Section, encompassing the Washington, D.C. metropolitan area,  includes the nearby Maryland and northern Virginia suburban areas; and the Chesapeake Section, including the Potomac Valley north of the Washington Metropolitan area and eastward to the Susquehanna River and the Eastern Shore, which includes the metropolitan Baltimore area.  The sections were one until the Potomac Section evolved into a separate section in the early 1980s.

    The Potomac Section web site intends to keep its members, friends, community, and its national, parent association informed of its many activities.  The section provides its members continuing education and networking opportunities through its monthly section meetings that are held during the school year, from September through May; some are joint meetings with other professional associations, as Health Physics Society, American Association of Safety Engineers, Occupational Nurses Association, and the Chesapeake Area Biological Safety Association.  In addition, the section routinely sponsors a professional development conference each year, inviting members of other professional associations to attend, and sponsors awards and provides judges for local middle school and high school science fairs.
