This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Prompted by a $10 million Congressional allocation to identify supplemental actions to protect the Columbia River from groundwater contamination beneath the Hanford Reservation, the U.S. Department of Energy (DOE) Environmental Management (EM) Office of Clean-up Technology identified twenty-three potential technical projects and then down-selected ten of these for further evaluation. An independent expert peer review was conducted for the ten down-selected proposals. The review panel consisted of twenty-three recognized subject matter experts that broadly represented academia, industry, and federal laboratories. Of the initial ten proposals reviewed, one was given unconditional support, six were given conditional support, and three were not supported as proposed. Three additional proposals were then submitted by DOE for review--these proposals were structured, in part, to respond to the initial round of technical peer review comments. Peer reviews of these additional proposals provided conditional support. For those proposals that received conditional support, DOE requested specific implementation and work plans and assessed whether the plans adequately addressed the technical conditions identified by the review panel. The final list of technology proposals receiving support, or conditional support, primarily focused on understanding and reducing the potential impacts of uranium, chromium, and strontium from facilities adjacent to the Columbia River, with a secondary focus on understanding and limiting the future Columbia River impacts from the large carbon tetrachloride groundwater plume underlying and downgradient of the Hanford Central Plateau facilities. The results and recommendations of the peer reviews informed the final DOE project selections and supported implementation of the selected projects to protect the Columbia River and address groundwater contamination at Hanford.

Download or read book Columbia River Impact Evaluation Plan written by and published by . This book was released on 1993 with total page 147 pages. Available in PDF, EPUB and Kindle. Book excerpt: As a result of past practices, four areas of the Hanford Site (the 100, 200, 300, and 1100 Areas) have been included on the US Environmental Protection Agency's (EPA's) National Priorities List (NPL) under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980. To accomplish the timely cleanup of the past-practice units, the Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement), was signed by the Washington State Department of Ecology (Ecology), EPA, and the US Department of Energy (DOE). To support the Tri-Party Agreement, milestones were adopted. These milestones represent the actions needed to ensure acceptable progress toward Hanford Site compliance with CERCLA, RCRA, and the Washington State Hazardous Waste Management Act of 1976. This report was prepared to fulfill the requirement of Tri-Party Agreement Milestone M-30-02, which requires a plan to determine cumulative health and environmental impacts to the Columbia River. This plan supplements the CERCLA remedial investigations/feasibility studies (RI/FS) and RCRA facility investigations/corrective measures studies (RFI/CMSs) that will be undertaken in the 100 Area. To support the plan development process, existing information was reviewed and a preliminary impact evaluation based on this information was performed. The purpose of the preliminary impact evaluation was to assess the adequacy of existing data and proposed data collection activities. Based on the results of the evaluation, a plan is proposed to collect additional data or make changes to existing or proposed data collection activities.

Available in PDF, EPUB and Kindle. Book excerpt: Along the remote shores of the Columbia River in southeast Washington state, a race is on. Fluor Hanford, a prime cleanup contractor to the U.S. Department of Energy (DOE) at the Hanford Site, is managing a massive, multi-faceted project to remove contaminants from the groundwater before they can reach the Columbia. Despite the daunting nature and size of the problem--about 80 square miles of aquifer under the site contains long-lived radionuclides and hazardous chemicals--significant progress is being made. Many groups are watching, speaking out, and helping. A large. passionate, diverse, and geographically dispersed community is united in its desire to protect the Columbia River--the eighth largest in the world--and have a voice in Hanford's future. Fluor Hanford and the DOE, along with the US. Environmental Protection Agency (EPA) and the Washington Department of Ecology (Ecology) interact with all the stakeholders to make the best decisions. Together, they have made some remarkable strides in the battle against groundwater contamination under the site.

Book excerpt: This data summary report summarizes the investigation results to evaluate the nature and distribution of Hanford Site-related contaminants present in the Columbia River. As detailed in DOE/RL-2008-11, more than 2,000 environmental samples were collected from the Columbia River between 2008 and 2010. These samples consisted of island soil, sediment, surface water, groundwater upwelling (pore water, surface water, and sediment), and fish tissue.

Download or read book Remedial Investigation Work Plan for Hanford Site Releases to the Columbia River written by and published by . This book was released on 2008 with total page 456 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Cleanup of contaminated soil and groundwater at the Hanford Site is under way and is striving to prevent further contaminants from reaching the Columbia River. However, some contaminants have already been released to the Columbia River from past discharges that occurred during the Hanford Site weapons production mission from 1943 to 1989. Waste disposal practices also resulted in release of contaminants to the soil. Some of the contaminants have moved from the soil into groundwater that lies beneath the Hanford Site, then moved with the flow of groundwater into the Columbia River where it comes up through the river bottom, or upwells. It is important to understand what contaminants are present, how concentrated they are, and where they are located at the present time because they may have undesirable effects on humans, animals, and plants that use or live in the Columbia River. The purpose and scope of this work plan is to describe the initial work to: Collect and analyze samples to identify what Hanford Site-related contaminants are present in the Columbia River, what their concentrations are, and where they are located; Use the sample results to estimate the current risk to humans, animals, and plants if they are exposed to Hanford Site-related contaminanats while they use or live in the Columbia River; Determine whether or not any cleanup actions are needed to lower the risk to humans, animals, and plants from being exposed to Hanford Site-related contaminants."--From executive summary (page ES-1).
Download or read book Hydrogeologic Controls on Ground water and Contaminant Discharge to the Columbia River Near the Hanford Townsite written by and published by . This book was released on 1992 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study is to quantify ground-water and contaminant discharge to the Columbia River in the Hanford Townsite vicinity. The primary objectives of the work are to: describe the hydrogeologic setting and controls on ground-water movement and contaminant discharge to the Columbia River; understand the river/aquifer relationship and its effects on contaminant discharge to the Columbia River; quantify the ground-water and contaminant mass discharge to the Columbia River; and provide data that may be useful for a three-dimensional model of ground-water flow and contaminant transport in the Hanford Townsite study area. The majority of ground-water contamination occurs within the unconfined aquifer; therefore, ground-water and contaminant discharge from the unconfined aquifer is the emphasis of this study. The period of study is primarily from June 1990 through March 1992.
