Fort McClellan is the nation’s first Base Realignment and Closure (BRAC) site contaminated with munitions and explosives of concern (MEC) to achieve early transfer from the U.S. Army. In addition to environmental consulting services, Matrix also self-performs MEC remediation; the firm conducted the overall operations management of the Fort McClellan site. Matrix subdivided the MEC contaminated areas into multiple munitions response sites (MRSs) and sub-tracts based on land use, road construction projects, infrastructure development priorities, and quantity-distance arcs. This prioritization of the site’s remediation allowed the redevelopment and resale of the property to proceed.

Matrix successfully completed the remediation of over 2,000 acres of heavily wooded, steep sloped terrain containing multiple former ordnance and chemical weapons training ranges and rendered safe over 10,000 munitions. Clearance to depth areas were prosecuted by DGM-based clearances, and clearance to 1-foot areas were prosecuted by handheld mag and dig operations. MEC remediation was completed ahead of schedule and within the client’s budget on a firm-fixed price basis.

As part of this innovative remediation approach in clearance to depth areas, Matrix implemented a low-cost, 6-inch aggressive analog clearance step to eliminate metallic clutter, thereby reducing the number of geophysical anomalies and overall clearance costs. Matrix also assigned experienced geophysicists as essential personnel for contemporaneous in-grid QC and implemented 100% in-grid QC hole checks using an EM-61. This dramatically reduced the number of QC failures and increased clearance to depth productivity by putting more UXO technicians on shovels.

Matrix grubbed all areas undergoing clearance to 1-foot which had the effect of improving overall workmanship, efficiency, and production. Matrix also conducted a prescribed burn and surface clearance in a heavily contaminated 40mm grenade sensitive fuze range and rocket launcher area.
