Summary Information
(last updated on: 9/29/2021 7:53:54 AM)
[Sept 2021] The McCormick and Baxter site is located on the northeast shore of the Willamette River in North Portland. The site includes 41 acres of land and 23 acres of sediments beneath the Willamette River. McCormick and Baxter Creosoting Company operated between 1944 and 1991, treating wood products with creosote, pentachlorophenol, and inorganic (arsenic, copper, chromium, and zinc) preservative solutions. Historically, process wastewaters were discharged directly to the Willamette River, and other process wastes were dumped in several areas of the site. Remedial investigations revealed the presence of significant concentrations of wood-treating chemicals in soil and groundwater at the site, and in river sediments adjacent to the site. Remedies to contain site contaminants were completed in 2005. Extensive monitoring, conducted since 2005 demonstate that the site remedies are functioning to meet the clean-up objectives required by the site Record of Decision (ROD).
The Soil and Sediment operable units are currently Operational and Functional, while the Groundwater operable unit is in Operational and Maintance mode. Please see EPA's Website (link below) for addtional information.
