Upper Columbia River Remedial Investigation & Feasibility Study
EPA is studying contamination in the Columbia River from the U.S./Canada border to the Grand Coulee Dam and surrounding upland areas. The study is called a Remedial Investigation and Feasibility Study (RI/FSRI/FSThe RI/FS is the step in the Superfund cleanup process that is conducted to gather sufficient information to support the selection of a site remedy that will reduce or eliminate the risks associated with contamination at the site. The RI involves site characterization -- collection of data and information necessary to characterize the nature and extent of contamination at the site. The RI also determines whether the contamination presents a significant risk to human health or the environment. The FS focuses on the development of specific response alternatives for addressing contamination at a site.).
Past studies by federal and state agencies have shown increased levels of heavy metals such as arsenic, lead, cadmium, copper, mercury and zinc, and other contaminants like dioxins and furans.
In August 1999, the Colville Confederated Tribes petitioned EPA to conduct an assessment of environmental contamination in the Upper Columbia River. The petition expressed concerns about risks to people’s health and the environment from contamination in the river.
In 2001, EPA collected samples of river sediment to learn more about the types and amounts of pollution that exists. The results showed that contamination is present in the lake and river sediments, and that a more detailed investigation is needed to evaluate possible risks to human health and the environment.
In 2006, Teck American, Inc. signed an agreement with EPA to pay for the RI/FS.
- Fact sheets
- Technical documents
- Enforcement documents
- Administrative Records (What's an Administrative RecordAdministrative RecordA compilation of documents supporting an administrative action; under Superfund, administrative actions often compel Potentially Responsible Parties (PRPs) to undertake or pay for hazardous waste site cleanups.?)
Many documents are also available on Teck American's Upper Columbia River Project website.Exit
For your convenience, information about this project is also available at seven locations throughout the project area. Each location has the same information, including full copies of draft and final technical documents, fact sheets, and other information about the site.

Community Technical Assistance
Our Technical Assistance Grant (TAG) program helps communities participate in cleanup decision-making. It provides funding to community groups to contract their own technical advisor to interpret and explain technical reports, site conditions, and EPA’s proposed cleanup proposals and decisions. An initial grant up to $50,000 is available to qualified community groups.
EPA has awarded Citizens for a Clean Columbia with a technical assistance grant funded by Teck American to participate in the RI/FS process. For more information, contact Citzens for a Clean Columbia.Exit
