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.

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 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 1993 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intent and scope of the work plan are to assemble all data necessary to facilitate selection of remediation alternatives for the sites in Bear Creek Valley Operable Unit 1 (BCV OU 1) such that the risk to human health and the environment is reduced to acceptable levels based on agreements with regulators. The ultimate goal is to develop a final Record Of Decision (ROD) for all of the OUs in BCV, including the integrator OU. However, the initial aim of the source OUs is to develop a ROD for interim measures. For source OUs such as BCV OU 1, data acquisition will not be carried out in a single event, but will be carried out in three stages that accommodate the schedule for developing a ROD for interim measures and the final site-wide ROD. The three stages are as follows: Stage 1, Assemble sufficient data to support decisions such as the need for removal actions, whether to continue with the remedial investigation (RI) process, or whether no further action is required. If the decision is made to continue the RI/FS process, then: Stage 2, Assemble sufficient data to allow for a ROD for interim measures that reduce risks to the human health and the environment. Stage 3, Provide input from the source OU that allows a final ROD to be issued for all OUs in the BCV hydrologic regime. One goal of the RI work plan will be to ensure that sampling operations required for the initial stage are not repeated at later stages. The overall goals of this RI are to define the nature and extent of contamination so that the impact of leachate, surface water runoff, and sediment from the OU I sites on the integrator OU can be evaluated, the risk to human health and the environment can be defined, and the general physical characteristics of the subsurface can be determined such that remedial alternatives can be screened.
