This book was released on 1998 with total page 775 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the BRA is twofold. First, the BRA provides an evaluation of the potential threat to human health and the environment associated with the release or potential release of constituents of concern from the ravines and Beach Area study areas of the Surplus OU at Fort Sheridan. The primary objective of this evaluation is to identify constituents of potential concern (COPCs) and exposure pathways, conduct a toxicity assessment for each COPC, conduct an exposure assessment, and characterize potential risks to human and environmental receptors. The BRA summarizes and interprets data collected during the RI to characterize the COPCs, describe constituent migration pathways, identify potential human and environmental exposure pathways, and assess current and future adverse effects on human health and the environment under the no action alternative. The second purpose of the BRA is to evaluate the need for a feasibility study (FS). This evaluation focuses on an evaluation of those potential risks greater than the acceptable range. This analysis will identify those constituents of concern and the affected media that drive the need for an FS.

This book was released on 1998 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document is comprised of two separate parts: the Ravines and Beach Area Study Areas of the Surplus Operable Unit (OU) Remedial Investigation (RI) Report and the Ravines and Beach Area Study Areas of the Surplus OU Baseline Risk Assessment (BRA). The RI presents the history of the Surplus OU; its geographic, hydrogeologic, and demographic setting; and a brief discussion of the methodologies used to collect the data evaluated in the report. The report also presents the collected data, establishes their validity and usability, and then evaluates the data to establish the nature and extent of the various affected environmental media (i.e., sediment, surface water, and groundwater) in the ravines and Beach Area study areas. The BRA evaluates the detected constituents to establish a list of constituents of potential concern (COPCs). The BRA identifies complete exposure pathways and those receptors potentially exposed to COPCs through these pathways. The BRA also evaluates whether the COPCs detected in the various environmental media in the ravines and Beach Area study areas pose a potential unacceptable risk to human health and the environment. The BRA concluded that the concentrations of COPCs in the various environmental media do not pose an unacceptable risk to human health or the environment.

This book was released on 1998 with total page 695 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fort Sheridan performed validation of analytical data that were collected during the Phase I Remedial investigation (RI) in 1990 to 1991. As required by the Final Overall Quality Assurance Project Plan Remedial Investigation/ Feasibility Study, Fort Sheridan, Illinois (OQAPP), Environmental Science & Engineering, Inc. (ESE), 1995, the validation was performed in accordance with the U.S. Environmental Protection Agency (USEPA) Contract Laboratory National Functional Guidelines. The results of the validation can be found in detail in the Final Data Validation Report (ECG, April 1996). The data validation process resulted in some of the data being assigned qualifiers "R" (meaning rejected) and "J" (meaning estimated). The significance of these two qualifiers on data usability for the RI was discussed between representatives of Fort Sheridan, USEPA, Illinois EPA, the U.S. Army Environmental Center (USAEC), and ESE. It was determined from this discussion and regulatory comments that resampling of most of the rejected (R-flagged) data would be conducted to replace the Phase I data. Also, at least 10 percent of the J-flagged samples would be resampled/ reanalyzed and compared with the Phase I results to provide an indication of overall data quality.

This book was released on 1996 with total page 693 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the findings of an investigation into contamination of the Clinch River and Poplar Creek near the US Department of Energy's (DOE's) Oak Ridge Reservation (ORR) in eastern Tennessee. For more than 50 years, various hazardous and radioactive substances have been released to the environment as a result of operations and waste management activities at the ORR. In 1989, the ORR was placed on the National Priorities List (NPL), established and maintained under the federal Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA). Under CERCLA, NPL sites must be investigated to determine the nature and extent of contamination at the site, assess the risk to human health and the environment posed by the site, and, if necessary, identify feasible remedial alternatives that could be used to clean the site and reduce risk. To facilitate the overall environmental restoration effort at the ORR, CERCLA activities are being implemented individually as distinct operable units (OUs). This document is the combined Remedial Investigation and Feasibility Study Report for the Clinch River/Poplar Creek OU.

Book excerpt: This document contains appendices A (water characterization), B (sediment characterization), C (biota Characterization), D (applicable or relevant and appropriate requirements) from the combined Remedial Investigation/Feasibility Study Report for the Clinch River/Poplar Crack (CR/PC) Operable Unit (OU). The CR/PC OU is located in Anderson and Roane Counties, Tennessee and consists of the Clinch River and several of its embayments in Melton Hill and Watts Bar Reservoirs. These waters have received hazardous substances released over a period of 50 years from the US Department of Energys̀ Oak Ridge Reservation (ORR), a National Priority List site established under the Comprehensive Environmental Response, Compensation, and Liability Act. A remedial investigation has been conducted to determine the current nature and extent of any contamination and to assess the resulting risk to human health and the environment. The feasibility study evaluates remedial action alternatives to identify any that are feasible for implementation and that would effectively reduce risk. Historical studies had indicated that current problems would likely include 137Cs in sediment of the Clinch River, mercury in sediment and fish of Poplar Creek and PCBs and pesticides in fish from throughout the OU. Peak releases of mercury and 137Cs occurred over 35 years ago, and current releases are low. Past releases of PCBs from the ORR are poorly quantified, and current releases are difficult to quantify because levels are so low. The site characterization focused on contaminants in surface water, sediment, and biota. Contaminants in surface water were all found to be below Ambient Water Quality Criteria. Other findings included the following: elevated metals including cesium 137 and mercury in McCoy Branch sediments; PCBs and chlordane elevated in several fish species, presenting the only major human health risk, significant ecological risks in Poplar Creek but not in the Clinch River.
