Kansas Army Ammunition Plant – Munitions and Explosives Decontamination & Demolition

Matrix self-performed a wide range of tasks under this Environmental Services Cooperative Agreement, including munitions response, building decontamination and demolition, and soil remediation at the former munitions manufacturing lines, commonly referred to as load lines. Efforts involved building clearances in locations where munitions items were removed from buildings and work areas, decontamination for explosives contamination, demolition where soil contamination was present under slabs, excavation, and disposal of contaminated soils to close Resource Conservation and Recovery Act (RCRA) permitting units and remove the parcels from the RCRA permit.

Tasks also included performing in situ groundwater remediation, assisting with permit modifications, conducting inspections and well maintenance, mowing landfills and RCRA permitted units, and conducting surface water and groundwater sampling. Matrix has safely provided munitions response work at the Kansas Army Ammunition Plant since 2009 without a single OSHA-reportable safety incident.

Throughout the service period, Matrix has utilized innovative solutions to solve complex problems. As an example, our team used specialized shaped charges to remove sensitive explosives residue such as lead azide and mercury fulminate from piping. We built and operated a 1 million BTU high-temperature thermal unit to treat explosives by superheating whole buildings, as well as piping from all buildings. This process allowed 97% of all metal to be recycled. Matrix also used high-pressure water-jet equipment to strip PCB paint from concrete walls and steel and to safely and remotely cut piping that could potentially contain explosives residue. We designed, built, and operated a steam cleaning system that treated and recycled rinse water, reducing the volume of water that required disposal by 95%.
