Analysis of stream bed sediments of Four Mile Creek

Until 1988, solutions containing nitric acid, odium hydroxide, low levels of radionuclides (mostly tritiated water) and some metals were discharged to unlined seepage basins at the F and H Areas of the Savannah River Site (SRS) as part of normal operations. The basins are now being closed according to the Resource Conservation and Recovery Act (RCA). As part of the closure, a Part B Post-Closure Care Permit is being prepared. The Part B permit requires information on contaminant concentrations in stream bed sediments in the adjacent Four Mile Creek, which are reported herein. 5 refs., 1 fig., 2 tabs

Analysis of soil and water at the Four Mile Creek seepline near the F- and H-Areas of SRS

Several soil and water samples were collected along the Four Mile Creek (FMC) seepline at the F and H Areas of the Savannah River Site. The samples were analyzed for concentrations of metals, radionuclides, and inorganic constituents. The results of the analyses are summarized for the soil and water samples

Technology status report: Off-gas treatment technologies for chlorinated volatile organic compound air emissions

The purpose of this document is to review technologies for treatment of air streams that contain chlorinated volatile organic compounds (CVOCS) and to describe a Department of Energy Office of Technology Development program that is planned to demonstrate innovative technologies for the abatement of CVOC emissions. This report describes the first phase of testing of off-gas treatment technologies. At least one more phase of testing is planned. Guidance for the preparation of this document was provided by a predecisional draft outline issued by the Department of Energy's Office of Technology Development. The report is intended to evaluate the technical and regulatory aspects, public acceptance, and estimated costs of technologies selected for development and testing. These technologies are compared to currently practiced or baseline methods for treatment of CVOC-laden airstreams. A brief overview is provided rather than detailed cost and data comparisons because many of these technologies have not yet been field tested. A description of other promising technologies for the treatment of CVOC emissions is also included. Trichloroethylene (TCE) and perchloroethylene (PCE) were used for industrial cleaning and solvent applications for several decades. These chemicals can be classified as CVOCS. As a result of past standard disposal practices, these types of compounds are persistent groundwater and soil contaminants throughout the United States and the Department of Energy Complex

Subsurface stratigraphy and structure of A/M area at the Savannah River Site, Aiken County, South Carolina

This report is a study of the stratigraphy and structure of the A/M Area Hazardous Waste Management Facility Post-Closure Care Permit process on the Savannah River Site. The data from the lithologic and geophysical logs of 93 wells is the basis of this analysis

Savannah River Laboratory Seepage Basins: Waste site assessment report

This Waste Site Assessment for the SRL Seepage Basins is the second in a series of documents being prepared to support development of an appropriate closure plan for these basins. The closure of these basins will be designed to provide protection to human health and the environment and to meet the provisions of the Consent Decree. A Technical Data Summary for these basins has already been submitted as part of the Consent Decree. This Site Assessment Report includes a waste site characterization, and a discussion of closure options for the basins. A closure option is recommended in this report, but details of the recommended closure are not provided in this report since they will be provided in a subsequent closure plan. The closure plan is the third document required under the Consent Decree. 18 refs., 16 figs., 10 tabs

Analysis of soil and water at the Four Mile Creek seepline near the F H Areas of SRS

Until 1988, solutions containing sodium hydroxide, nitride acid, low levels of radionuclides (mostly tritiated water) and some metals were discharged to unlined seepage basins at the F and H Areas of the Savannah River Site (SRS) as part of normal operations (Killian et al, 1987a,b). The basins are now being closed according to the Resource Conservation and Recovery Act (RCRA). As part of the closure, a Part B Post-Closure Care Permit is being prepared. The information included in this report will fulfill some of the data requirements for that Part B permit. Several soil and water samples were collected along the Four Mile Creek (FMC) seepline at the F H Areas of the Savannah River Site. The samples were analyzed for concentrations of metals, radionuclides, and inorganic constituents. The goal of the work reported herein is to document the impacts from the basins of FMC has been completed in a phased approach

Analysis of soil and water at the Four Mile Creek seepline near the F H areas of SRS

Several soil and water samples were collected along the Four Mile Creek (FMC) seepline at the F H Areas of the Savannah River Site. The samples were analyzed for concentrations of metals, radionuclides, and inorganic constituents. The results of the analyses are summarized below for the soil and water samples

A ground water flow model for the A/M Area of the SRS

In 1984 and 1985, a quasi three-dimensional groundwater flow model was developed for the A/M Area (Savannah River Laboratory Complex) of the Savannah River Site to assist in the design of a groundwater recovery well network to remediate groundwater contaminated with chlorinated hydrocarbon solvents. In 1986, the existing groundwater flow model was used to evaluate the effectiveness of groundwater remediation systems. Since the original model was developed, additional monitoring wells have been installed, the understanding of the hydrogeologic system has improved and the horizontal and vertical extent of the contamination in the groundwater systems has been better defined. The objective of this study is to update and improve the existing A/M Area groundwater flow model by incorporating recent hydrologic information. The new model is calibrated to 1989--1990 groundwater levels and surface water flows. The model area is approximately 31 square miles and encompasses a manufacturing and processing area designated the A/M Area, a previous waste effluent disposal basin and overflow to a natural depression (Lost Lake), and several surface water features. The simulations are run on 80386-based personal computer using the public-domain groundwater flow code MODFLOW. This calibrated coarse-grid model is a base model. Specific areas of interest can be further discritized to provide more detailed and accurate water level elevations for use in particle tracking and capture analysis. The particle tracking and capture analysis are used to evaluate the groundwater contamination capture and removal capacity of proposed recovery wells

Solubility of carbon dioxide and ethane in lemon oil at elevated pressures

The solubility of ethane and carbon dioxide in lemon oil at elevated pressures has been measured using a variable volume cell, over temperature ranges of 298 - 308 K and 303 - 313 K, respectively, at pressures from 0.44 to 8.75 MPa. Partial liquid miscibility was not observed at any concentration measured. Molar densities of the saturated liquid mixtures are also reported.
