The Manhattan Project began contracting the Baker Brothers in 1943 to machine uranium metal rods into slugs for the Hanford Pile. This was a temporary contract that would end once Hanford's own facilities were up and running. The rods to be machined by Baker Brothers were first extruded by Revere Copper and Brass Corp.

The uranium machined and shaped was natural; neither enriched or depleted uranium from possessed uranium metals. The radioactive of note would have been uranium-238. Records are unavailable for the exact amount machined at the site. Documents exists that state that Baker Brothers was expected to machine around 90 tons of rods between January and May of 1944. It is inconclusive if they processed any additional uranium, but it is likely that all of the X-10 extrusions from Revere Copper and Brass were machined at Baker Brothers. If so, then over 300 tons of metal could have been handled at the Toledo Site.

In 1944 the Manhattan Project ended the contract with Baker Brothers. Baker Brothers liquidated their assets and the property was sold to two independent interests. Reports
indicated that workers kept a uranium slug in the shop area for several years after the conclusion of the contract.

In 1989 the DOE surveyed the area and found localized areas of residual uranium contamination above applicable guidelines. The area was resurveyed a year later and was recommended for inclusion in the Formerly Utilized Sites Remedial Action Program (FUSRAP).

When a portion of the property was sold in 1992 the new owner contacted the DOE for information about the radiological status of the property. Due to this inquiry, the DOC found out that soil and debris that was could have been contaminated with residual uranium had been moved from the site to a 7 acre residential property about 15 miles northwest of Toledo to be used as fill material. The radioactively contaminated soil and debris was evacuated from the premises using both earth-moving equipment and manually. Approximately 1,920 cubic yards of contaminated material (soils, gravel, asphalt concert, grass, stumps, shrubbery) were removed and transported to a facility in Clive, Utah, 80 miles west of Salt Lake City.

Remediation of the Toledo Site was completed in September 1995 removing 356 cubic yards of low-level radioactive waste and 5 cubic yards of mixed waste generated from area.
