A study on chemical interactions between waste fluid, formation water, and host rock during deep well injection (open access)

A study on chemical interactions between waste fluid, formation water, and host rock during deep well injection

A new disposal well was drilled in the vicinity of an injection well that had been in operation for 12 years. The drilling activities provided an opportunity to assess the fate and transport of waste products injected in the nearby well, and the impact, if any, on the host geologic formation. The origin of the fluid collected while drilling the new well and the interaction between injected waste and the formation were investigated using analyses of formation waters, waste, and formation minerals, by applying traditional graphical methods and sophisticated numerical models. This approach can be used to solve a wide range of geochemical problems related to deep well injection of waste. Trilinear Piper diagrams, Stiff diagrams, and correlation plots show that the chemical characteristics of recovered fluid at the new well are similar to those of formation water. The concentrations of most major constituents in the fluid appear diluted when compared to formation water sampled at other locations. This could be explained by mixing with waste, which is less saline than formation water. However, the waste injected near the new well consists primarily of ammonia and sulfate, and these waste constituents are not found at concentrations elevated enough to suggest …

Oral History Interview with L. C. Finger, June 14, 2004 (open access)

Oral History Interview with L. C. Finger, June 14, 2004

The National Museum of the Pacific War presents an oral interview with L.C. Finger. Finger was born in Garner, Texas. Drafted into the Army in 1943, he was sent to Camp Wolters, Texas for three weeks of basic training. He was then sent to Camp Mackall, North Carolina where he joined the 11th Airborne Division, volunteering for parachute training. He made five practice jumps before deploying overseas. Arriving at Leyte in June 1944 they made three practice jumps and conducted routine patrols. He recalls in December a Japanese force came out of the jungles and attacked an airfield and an engineering group killing many Americans. Elements of Finger’s division searched and were successful in finding and destroying the enemy force. That evening the Japanese dropped paratroopers to take the local airfield and he tells of seeing them come down, highlighted by white parachutes, enabling the Americans to kill many of them as they landed. The division retook the airfield the next day. While participating in the action, Finger was seriously wounded by a Japanese sniper. He was taken to an aid station and then to a field hospital where doctors removed his right leg. He was taken to Biak, New …

Metropolitan Statistical Areas: New Standards and Their Impact on Selected Federal Programs (open access)

Metropolitan Statistical Areas: New Standards and Their Impact on Selected Federal Programs

A letter report issued by the General Accounting Office with an abstract that begins "For the past 50 years, the federal government has had a metropolitan area program designed to provide a nationally consistent set of standards for collecting, tabulating, and publishing federal statistics for geographic areas in the United States and Puerto Rico. Before each decennial census, the Office of Management and Budget (OMB) reviews the standards to ensure their continued usefulness and relevance and, if warranted, revises them. While designed only for statistical purposes, various federal programs use the statistical areas to determine eligibility and to allocate federal funds. OMB advises agencies to carefully review program goals to ensure that appropriate geographic entities are used in making these decisions. GAO was asked to examine the process used for developing the OMB standards issued in 2000 and their effects on certain federal programs. Specifically, GAO agreed to report on (1) the process used to develop the 2000 standards, (2) how the 2000 standards differed from the 1990 standards, (3) how the application of the standards affected the geographic distribution of counties into statistical areas, and (4) the effect of standards on the eligibility and funding allocations for four federal …

Induced Polarization with Electromagnetic Coupling: 3D Spectral Imaging Theory, EMSP Project No. 73836 (open access)

Induced Polarization with Electromagnetic Coupling: 3D Spectral Imaging Theory, EMSP Project No. 73836

This project was designed as a broad foundational study of spectral induced polarization (SIP) for characterization of contaminated sites. It encompassed laboratory studies of the effects of chemistry on induced polarization, development of 3D forward modeling and inversion codes, and investigations of inductive and capacitive coupling problems. In the laboratory part of the project a physico-chemical model developed in this project was used to invert laboratory IP spectra for the grain size and the effective grain size distribution of the sedimentary rocks as well as the formation factor, porosity, specific surface area, and the apparent fractal dimension. Furthermore, it was established that the IP response changed with the solution chemistry, the concentration of a given solution chemistry, valence of the constituent ions, and ionic radius. In the field part of the project, a 3D complex forward and inverse model was developed. It was used to process data acquired at two frequencies (1/16 Hz and 1/ 4Hz) in a cross-borehole configuration at the A-14 outfall area of the Savannah River Site (SRS) during March 2003 and June 2004. The chosen SRS site was contaminated with Tetrachloroethylene (TCE) and Trichloroethylene (PCE) that were disposed in this area for several decades till the …

Techniques for assessing the performance of in situ bioreduction and immobilization of metals and radionuclides in contaminated subsurface environments (open access)

Techniques for assessing the performance of in situ bioreduction and immobilization of metals and radionuclides in contaminated subsurface environments

Department of Energy (DOE) facilities within the weapons complex face a daunting challenge of remediating huge below inventories of legacy radioactive and toxic metal waste. More often than not, the scope of the problem is massive, particularly in the high recharge, humid regions east of the Mississippi river, where the off-site migration of contaminants continues to plague soil water, groundwater, and surface water sources. As of 2002, contaminated sites are closing rapidly and many remediation strategies have chosen to leave contaminants in-place. In situ barriers, surface caps, and bioremediation are often the remedial strategies of chose. By choosing to leave contaminants in-place, we must accept the fact that the contaminants will continue to interact with subsurface and surface media. Contaminant interactions with the geosphere are complex and investigating long term changes and interactive processes is imperative to verifying risks. We must be able to understand the consequences of our action or inaction. The focus of this manuscript is to describe recent technical developments for assessing the performance of in situ bioremediation and immobilization of subsurface metals and radionuclides. Research within DOE's NABIR and EMSP programs has been investigating the possibility of using subsurface microorganisms to convert redox sensitive toxic metals …

Upscaling Radionuclide Retardation?Linking the Surface Complexation and Ion Exchange Mechanistic Approach to a Linear Kd Approach (open access)

Upscaling Radionuclide Retardation?Linking the Surface Complexation and Ion Exchange Mechanistic Approach to a Linear Kd Approach

The LLNL near-field hydrologic source term (HST) model is based on a mechanistic approach to radionuclide retardation-that is, a thermodynamic description of chemical processes governing retardation in the near field, such as aqueous speciation, surface complexation, ion exchange, and precipitation The mechanistic approach allows for radionuclide retardation to vary both in space and time as a function of the complex reaction chemistry of the medium. This level of complexity is necessary for near-field HST transport modeling because of the non-linear reaction chemistry expected close to the radiologic source. Large-scale Corrective Action Unit (CAU) models-into which the near-field HST model results feed-require that the complexity of the mechanistic approach be reduced to a more manageable form (e.g. Linear, Langmuir, or Freundlich sorption isotherms, etc). The linear sorption isotherm (or K{sub d}) approach is likely the most simple approach for large-scale CAU models. It may also be the most appropriate since the reaction chemistry away from the near field is expected to be less complex and relatively steady state. However, if the radionuclide retardation approaches in near-field HST and large-scale CAU models are different, they must be proved consistent. In this report, we develop a method to link the near-field HST and …

Natural Gas Flaring and Venting: Opportunities to Improve Data and Reduce Emissions

A letter report issued by the Government Accountability Office with an abstract that begins "Since 1995, the average price of natural gas in the United States has almost tripled as demand has grown faster than supply. Despite this increase, natural gas is regularly lost as it is burned (flared) and released into the atmosphere (vented) during the production of oil and gas. GAO was asked to (1) describe flaring and venting data and what the federal government could do to improve them; (2) report, on the basis of available information, on the extent of flaring and venting and their contributions to greenhouse gases; and (3) identify opportunities for the federal government to reduce flaring and venting."

Vadose Zone Contaminant Fate and Transport Analysis for the 216-B-26 Trench (open access)

Vadose Zone Contaminant Fate and Transport Analysis for the 216-B-26 Trench

The BC Cribs and Trenches, part of the 200 TW 1 OU waste sites, received about 30 Mgal of scavenged tank waste, with possibly the largest inventory of 99Tc ever disposed to the soil at Hanford and site remediation is being accelerated. The purpose of this work was to develop a conceptual model for contaminant fate and transport at the 216-B-26 Trench site to support identification and development and evaluation of remediation alternatives. Large concentrations of 99Tc high above the water table implicated stratigraphy in the control of the downward migration. The current conceptual model accounts for small-scale stratigraphy; site-specific changes soil properties; tilted layers; and lateral spreading. It assumes the layers are spatially continuous causing water and solutes to move laterally across the boundary if conditions permit. Water influx at the surface is assumed to be steady. Model parameters were generated with pedotransfer functions; these were coupled high resolution neutron moisture logs that provided information on the underlying heterogeneity on a scale of 3 inches. Two approaches were used to evaluate the impact of remedial options on transport. In the first, a 1-D convolution solution to the convective-dispersive equation was used, assuming steady flow. This model was used to …
