	springvalley homepage

During World War I, the U.S. Army conducted chemical warfare research at the site of the present Spring Valley neighborhood in Washington, DC. Chemical weapons were detonated in several areas during research and training operations. Chemical agents, including hazardous substances, ordnance, and explosive waste, were buried in parts of the area, which has since been developed. It is now occupied by residential homes and the American University campus.

Spring Valley is also known as American University and American University Experiment Station.
