Article Update on August 2017 incident.
Washington, D.C. Last month, five workers at 4825 Glenbrook Road (part of the Spring Valley project where the prior American University Experiment Station was located) were potentially exposed to an unknown chemical. The site crews are remediating WWI-era CWM at the site. Five of the seven workers exhibited symptoms of eye irritation and minor stomach issues. The workers were decontaminated onsite and reportedly all symptoms had subsided within an hour of the potential exposure. However, as a precaution, the workers were sent to George Washington University Hospital for medical monitoring and observation. All of the workers were released for work later that evening and all reported to work the next day.
The worksite where the possible exposure occurred was not shut down but has entered into a non-intrusive work pattern while a formal board of USACE, EPA and District of Environment and Energy (DOEE) officials investigates the incident. The board is expected to release a report at the end of October at which time a return to work phase will be announced.
