Demonstration of Electro-Osmotic Pulse and Dehumidification Technologies to Mitigate Corrosion in Earth Covered Magazines: Final Report on Project F08-AR23

The Department of Defense (DoD) maintains many earth covered magazines (ECMs) on its installations including tropical coastal marine properties. ECMs are used to store a wide variety of explosive ordnance. Coastal marine locations are exposed to extreme humidity, high rainfall, and a chloride-infused atmosphere. These conditions create a damp, highly corrosive environment inside ECMs and can severely damage the structures and their contents, and promote rapid, mold growth that is hazardous to human health. The objective of this demonstration project was to install and evaluate electro-osmotic pulse (EOP) and dehumidification (DH) technologies in an Army ECM on Guam to mitigate water intrusion and excessively high interior relative humidity (RH), respectively. The demonstration was intended to evaluate how effective this technology combination is at reducing corrosive and unhealthy conditions inside an ECM. Demonstration results were promising but mixed. The DH system held interior RH to 40%-60% while outdoor RH ranged from 85%-95%. However, the demonstration period was not long enough for the EOP system to reach equilibrium and fully stop seepage. Because the EOP success metric could not be validated for purposes of calculating the project return on investment, the reported return is based only on DH system performance.
