Hundreds of military or former military sites across the nation are contaminated with unexploded ordnance, discarded military munitions, and other munitions and explosives of concern. Clean up is expected to cost $35 billion. Geophysical anomaly classification is a new, cutting-edge technology, in which geophysical anomalies (e.g. scrap metal, unexploded ordnance, etc.) are detected on a site with buried munitions, and then, with the use of new instruments and advanced geophysics, the anomalies are classified underground in order to determine whether or not the individual items will be removed. The goal of this project is to provide guidance to environmental professionals concerning the design and implementation of a geophysical classification project, thereby increasing the scientific defensibility, effectiveness, and efficiency. This project produced a Web-based guidance document, “Geophysical Classification for Munitions Response (GCMR-2)”, “Geophysical Classification for Munitions Response Fact Sheets (GCMR-1)”, and Internet-based training course that describes the science behind geophysical classification, the latest geophysical classification instruments, the steps to be taken in the field and during data processing, and provide measures to allow the quality of the work to be assessed.
