Unalaska, AK – This summer, the U.S. Army Corps of Engineers will be conducting a remedial investigation at Fort Glenn, a former defense site on Umnak Island.

Fort Glenn was used as an army airfield and defense garrison during World War II, and reports have suggested that the island might be contaminated with mustard gas and other materials used for warfare. This summer, the Army Corps of engineers will look for areas where chemical warfare materials might have been stored through environmental sampling. It's the first time the corps has done this sort of work since 2004.

According to project manager Carey Cossaboom, ranching operations are not expected to be affected.

The corps will hold a meeting on the investigation at the Unalaska Public Library on May 17 at 6pm, where they will both provide information on the project and take public comment.
