EEGS is incorporated in the State of Colorado as a not-for-profit corporation and has approximately 650 members. The society's primary activity is its annual meeting. In addition, it develops and distributes a peer-reviewed scientific journal, as well as a newsletter, quarterly. It also publishes, markets, and distributes books and CD-ROMs on the application and use of geophysical technologies. 

The annual meeting of the organization, known as the Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP), is held in the late winter or early spring. Attendance over the last several years averages about 350. SAGEEP is internationally recognized as the leading conference on the practical application of shallow geophysics. It occurs over a 5-day period, with approximately 150 oral and poster presentations, several educational workshops, numerous vendor presentations, and a commercial exhibition. A set of proceedings, comprised of technical papers presented at the conference is distributed. SAGEEP pre-dates EEGS, and proceedings exist for every year starting with 1988. 

A peer-reviewed journal, Journal of Environmental and Engineering Geophysics (JEEG), is published quarterly and distributed via mail to the EEGS membership and academic libraries. Articles from recent issues (2005 forward) are available online to members of subscribing institutions through GeoScienceWorld (www.geoscienceworld.org). An electronic newsmagazine, FastTIMES, is also produced quarterly and is distributed via email and as a downloadable file through the society's web page. 

There are several student chapters in North America and Canada. In addition, EEGS maintains close ties with the near surface geophysics section (formerly EEGS-European Section) of the European Association of Geoscientists and Engineers, the Near-Surface Geophysics Section of the Society of Exploration Geophysicists, the Near-Surface Focus Group of the American Geophysical Union, and formal affiliated society agreements with several international professional societies.
