Site Description

The former Fort Ord, in Monterey County, California, is a closed installation that has an ongoing munitions response program managed by the U.S. Army Corps of Engineers (USACE) Sacramento District, on behalf of the Fort Ord Base Realignment and Closure (BRAC) Office. Fort Ord served as an active training facility for 77 years before closing in 1994.

The ESTCP demonstration is being conducted in Units 11 and 12, which are within the 476-acre Impact Area Munitions Response Area (MRA). Data collection is underway within a three to five acre subset of Units 11 and 12.

Suspected Munitions Present at the Demonstration Site

37mm, 40mm, 57mm, 60mm, 75mm, 90mm, 105mm, and 155mm projectiles

Demonstration Summary

Demonstrators are collecting MetalMapper (MM) data in dynamic and cued mode with the objective of identifying and classifying munitions. The demonstration site contains high anomaly densities and is suspected to contain a wide range of munitions sizes. Primary objectives of the demonstration are to test if MM dynamic surveys and advanced classification methods using cued data can identify large munitions items from a high clutter background that includes a wide range of suspected munitions. The demonstrator will apply advanced classification methods using the MM data to identify subsurface munitions. Industry standard objects (ISOs), used to simulate munitions, will be emplaced at the site as blind seeds. A subset of buried metallic items and the blind seeds will be dug to verify classification technology performance. Results of the data analysis from this demonstration will be posted as they become available.
