Health Assessment for Boise Cascade (BC) National Priorities List (NPL) Site, Fridley, Anoka County, Minnesota, Region 5. CERCLIS No. MND053417515

摘要

Boise Cascade is a 183-acre National Priorities List Site located in Anoka County, Fridley, Minnesota. The site was used by the Minnesota and Ontario Paper Company, which operated a plant for the treatment of wood with chemical preservatives (reportedly creosote and pentachlorophenol) between approximately 1921-1961. The site was used for wood storage and for the disposal of plant waste. Present owners of the site include Onan Corporation, which owns 133 acres. Approximately 3,000 people live within 4,000 feet of the site. Sampling and analysis of on-site soil and groundwater revealed a number of contaminants commonly associated with wood-treating operations including polynuclear aromatic hydrocarbons and pentachlorophenol. The highest levels of contaminants were found on the Onan property. Remediation was completed in 1986. Remedial actions included excavating and disposing of contaminated soil, placing clean fill in excavated areas, extracting and treating contaminated groundwater, surrounding the site with a security fence, and monitoring of air, ground water, and surface water within the site vicinity.
