This book was released on 1992 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over a 20-month period between September 1990 and April 1992, the Department of Energy (DOE), acting through Martin Marietta Energy Systems, Inc., managing contractor for the DOE Oak Ridge Field Office (DOE-OR), conducted a DOE-lead and DOE-funded time-critical removal action at the White Oak Creek Embayment (WOCE), pursuant to the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The time-critical removal action specifically consisted of the design and construction of a sediment-retention structure across the mouth of WOCE to prevent off-site migration of sediments contaminated by cesium (137Cs) into the Clinch River. Construction of a sediment-retention structure was completed in mid-April 1992. The purpose of this report is to meet the substantive requirements of 40 CFR 300.165 describing à̀ complete report on the removal operation and the actions taken. ̀̀This section of the NCP specifically addresses on-scene coordinator reports for the Environmental Protection Agency (EPA) Superfund-lead actions and includes several elements that are not applicable to this DOE-lead action. Only those sections that are pertinent and applicable are addressed in this final report.

Available in PDF, EPUB and Kindle. Book excerpt: White Oak Creek is the major surface water drainage throughout the Department of Energy (DOE) Oak Ridge National Laboratory (ORNL). Samples taken from the lower portion of the creek revealed high levels of Cesium 137 and lower level of Cobalt 60 in near surface sediment. Other contaminants present in the sediment included: lead, mercury, chromium, and PCBs. In October 1990, DOE, US Environmental Protection Agency (EPA), and Tennessee Department of Environment and Conservation (TDEC) agreed to initiate a time critical removal action in accordance with the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) to prevent the transport of the contaminated sediments into the Clinch River system. This paper discusses the environmental, regulatory, design, and construction issues that were encountered in conducting the remediation work.

This book was released on 1993 with total page 178 pages. Available in PDF, EPUB and Kindle. Book excerpt: Water quality monitoring activities that focused on the detection of resuspended sediments in the Clinch River were conducted in conjunction with the White Oak Creek Embayment (WOCE) time-critical Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) removal action to construct a sediment-retention structure at the mouth of White Oak Creek (WOC). Samples were collected by use of a 24-h composite sampler and through real-time water grab sampling of sediment plumes generated by the construction activities. Sampling stations were established both at the WOC mouth, immediately adjacent to the construction site, and at K-1513, the Oak Ridge K-25 Site drinking water intake approximately 9.6 km downstream in the Clinch River. Results are described.

Download or read book White Oak Creek Embayment Site Characterization and Contaminant Screening Analysis. Environmental Restoration Program written by and published by . This book was released on 1993 with total page 139 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analyses of sediment samples collected near the mouth of White Oak Creek during the summer of 1990 revealed 137Cs concentrations [> 106 Bq/kg dry wt (> 104 pCi/g dry wt)] near the sediment surface. Available evidence indicates that these relatively high concentrations of 137Cs now at the sediment surface were released from White Oak Dam in the mid-1950s and had accumulated at depositionalsites in the embayment. These accumulated sediments are being eroded and transported downstream primarily during winter low-water levels by flood events and by a combination of normal downstream flow and the water turbulence created by the release of water from Melton Hill Dam during hydropower generation cycles. This report provides a more thorough characterization of the extent of contamination in WOCE than was previously available. Environmental samples collected from WOCE were analyzed for organic, inorganic, and radiological contaminants in fish, water, and sediment. These results were used to conduct a human health effects screening analysis. Walkover radiation surveys conducted inside the fenced area surrounding the WOCE at summer-pool (741 ft MSL) and at winter-pool (733 ft MSL) level, indicated a maximum exposure rate of 3 mR h1 1 m above the soil surface.

This book was released on 1991 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 47 years, operations and waste disposal activities at Oak Ridge National Laboratory have resulted in the contamination of the White Oak Creek drainage system. The containments presenting the highest risk to human health and the environment are particle reactive and are associated with the soils and sediments in White Oak Creek. During floods, the erosion of these sediments results in the transport of contaminants out of the catchment into the Clinch River. A long-term strategy is required to monitor the movement of contaminated sediments and to predict the transport of these sediments that could occur during major floods. A monitoring program will provide the information required to (1) evaluate the existing off-site transport of contaminated sediments, (2) evaluate the need for short-term control measures, (3) set priorities for remediation of contaminated areas in White Oak Creek (4) verify the success of completed remedial actions intended to control the movement of contaminated sediments, and (5) develop a computer model to simulate the transport of contaminated sediments in White Oak Creek. A contaminant-transport model will be developed to (1) evaluate the potential for the off-site transport of contaminated sediments during major floods, (2) develop long term control measures and remediation solutions, (3) predict the impact of future land-use changes in White Oak Creek on the transport of contaminated sediment. This report contains a plan for the monitoring and modeling activities required to accomplish these objectives.
