Plum Brook Ordnance Works (PBOW), located near Sandusky, Ohio, produced trinitrotuluene (TNT), dinitrotuluene (DNT) and Pentolite from 1941 to 1944 for use during World War II. Currently the National Aeronautics and Space Administration (NASA) Glenn Research Center occupies the site.

Possession of the property was transferred to the Ordnance Department in 1946, then to the War Assets Department, and finally to the General Services Agency (GSA) in 1949. NASA acquired the property in 1963 and presently maintains and utilizes approximately 6,500 of the original 9,000 acres.

Numerous environmental investigations have been conducted at the site to determine the level of contamination from the ordnance manufacturing processes. Current investigations began in the early 1980s and since then 16 areas of concern (AOC) have been identified. Recent investigations conducted by U.S. Army Corps of Engineers (USACE) Huntington District have initiated remediation activities under the Defense Environmental Restoration Program for Formerly Used Defense Sites (DERP-FUDS). The USACE is the federal agency responsible for environmental restoration at Department of Defense installations. Huntington District USACE works closely with the Ohio Environmental Protection Agency (EPA), National Aeronautics and Space Administration (NASA) and the Restoration Advisory Board (RAB), a group of concerned citizens from the communities surrounding the PBOW area.

PBOW is located near Sandusky, Ohio, four miles south of the Lake Erie Port of Sandusky, and consists of 9,009.32 acres of land plus 1.35 acres for a pump station. Located primarily in Perkins Township, most of the southeastern portion of PBOW lies in Oxford Township. The eastern edge of the site extends into Huron and Milan Townships. The site is bounded by U.S Route 250 on the east, County Road 43 on the west, Bogart Road on the north and Mason Road on the south. Most of PBOW is situated on undisturbed forested land, while the area surrounding the site is rural and agriculturally developed.
