Geophysical Classification for Munitions Response Resources & Links

ITRC does not control information on external site links (see Terms of Service)

Geophysicists routinely use electromagnetic sensors to detect metallic items beneath the ground surface. At a munitions response site, these detected metallic items may be unexploded ordnance (UXO), discarded military munitions (DMM), or metallic debris. Recent advances in electromagnetic sensor technology enables the collection of additional data that geophysical analysts can use to estimate the depth, size, density, wall thickness, and shape of each buried item detected during a geophysical survey. Geophysical classification is the process of using this data to make a principled decision on whether the detected buried metal item needs to be excavated (i.e. is suspected of being UXO or DMM) or can be safely left in the ground. Using this geophysical classification process, munitions response efforts can be accelerated by focusing resources on the investigation of suspected munitions items and bypassing miscellaneous debris.

Fact Sheets

The ITRC Geophysical Classification for Munitions Response Team is developing a series of fact sheets designed to provide basic information about geophysical classification for munitions response.

The first fact sheet, Introduction to Geophysical Classification for Munitions Response, introduces regulators, stakeholders, and others to the basics on geophysical classification for munitions response.

The technical fact sheet provides an overview of the geophysical classification technology and process, the types of terrestrial sites where this technology may be applicable, and data quality considerations. This fact sheet benefits scientists, engineers, and other environmental professionals who are familiar with or have experience executing or managing munitions responses. This target audience may include, but is not limited to, state and federal environmental regulators as well as munitions response managers and technical staff.

A third fact sheet will provide an overview of regulatory considerations for the use of geophysical classification and will benefit regulators and others who need to understand regulator expectations regarding the use of geophysical classification. The fact sheet will also be published in 2013.

Training Modules

These on-demand videos provide training on the following: general information on munitions response and munitions response programs within the Department of Defense; the munitions response regulatory framework and process; an overview of munitions response technologies; an introduction to geophysical classification and the classification process; and a case study of a geophysical classification demonstration site. These training modules were presented in April 2012 at an ITRC Geophysical Classification for Munitions Response Team meeting.
