Abstract: Earth-covered magazines (ECMs) are used by the Army to store a wide variety of explosive ordinance. These munitions are subject to corrosion under humid conditions and during heavy rainfall. The objective of this project was to install dehumidification (DH) technology in two Earth Covered Magazines at Fort A.P. Hill, Virginia, to enhance the performance of the Electro-Osmotic Pulse (EOP) systems and collect performance and cost data to evaluate their combined efficacy during a one-year demonstration period. Controlling relative humidity (RH) would reduce the expense, damage, and impairment to readiness imposed by corrosion on stored munitions and could increase the design life of the ECM itself. EOP technology was previously installed in ECMs at Fort A.P Hill for corrosion control under a separate project. During the current project, the RH inside the two magazines was measured and recorded. An EOP system was operating in conjunction with a DH system in one bunker for part of the study’s duration. However, no conclusion can be made whether EOP added to the reduction in RH. The 30-year return on investment is projected to be 4.53, and using DH systems is recommended for critical storage facilities where high RH promotes corrosion or other degradation.
