6900 N EDGEWATER ROAD

The McCormick and Baxter site is a former wood treatment facility located on the Willamette River in Portland, Oregon. The site encompasses approximately 43 acres on land and 23 acres in the river. Wood treatment operations were conducted on the site between 1944 and 1991. Wood treating products used at the site include creosote/diesel oil mixtures, pentachlorophenol (PCP)/diesel oil mixtures, and a variety of water- and ammonia-based solutions containing arsenic, chromium, copper, and zinc. Between 1945 and 1969, wastewater and non-contact cooling water were discharged directly into the Willamette River. Prior to 1971, boiler water, stormwater, and oily wastes were disposed of in the western portion of the site. The facility ceased wood treating operations in 1991. Approximately 4,500 people live within one square mile of the site. Site Responsibility: This site is being addressed through state actions and federal funding.
