Interim Holding Facility (IHF)

The U.S. Army Corps of Engineers is storing World War I chemical weapons excavated from the nearby Spring Valley community inside this tent-like structure with the long air filtration unit. Contaminated soil is stored inside the blue barrels. This land is just north of Sibley Hospital and on the east side of Dalecarlia Reservoir. Dalecarlia Parkway is visible 310 feet away through the trees in back.
