Army Demolishing Building 130 

The U.S. Army has begun removing Building 130, which is located northeast of the Refuge Visitors Center. The building was known as the Environmental Analytical Laboratory, and was used to analyze soil, water, and air samples collected during the environmental clean-up of RMA. Since there is no further use for the building, the Army will remove it as part of a larger effort to reduce the Army’s footprint at RMA.
