Electrical impedance tomography of the 1995 OGI gasoline release

Description: Electrical impedance tomography (EIT) was used to image the plume resulting from a release of 378 liters (100 gallons) of gasoline into a sandy acquifer. Images were made in 5 planes before and 5 times during the release, to generate a detailed picture of the spatial as well as the temporal development of the plume as it spread at the water table. Information of the electrical impedance (both in phase and out of phase voltages) was used or several different frequencies to produce images. We observed little dispersion in the images either before or after the gasoline entered the acquifer. Likewise, despite some laboratory measurements of impedances, there was no evidence of a change in the reactance in the soil because of the gasoline.

Hydrologic Characterization Using Vadose Zone Monitoring Tools: Status Report

Description: Hydrologic characterization of the vadose zone (from soil surface to the underlying water table) is needed to assess contaminant migration from buried wastes. The Pacific Northwest National Laboratory, under contract with the U. S. Department of Energy's EM-50 (Subsurface Contamination Focus Area), and in collaboration with CH2MHILL Hanford Group, the Idaho National Engineering and Environmental Laboratory (INEEL), and Duratek Federal Services (DFS), deployed a suite of vadose-zone instruments at the Hanford Site near Richland, Washington. Several new instruments were tested.

Basement Flooding and Foundation Damage from Water-Table Rise in the East New York Section of Brooklyn, Long Island, New York

Description: From purpose and scope: The purpose and scope of this report is to present the factors that have caused the water-table rise in the East New York section of Brooklyn. The rising water table in Kings County is not sudden or new; it has a history of more than two decades. It will refocus attention on the problem of changing ground-water levels in areas where intensive ground-water pumping has ceased or is occurring.

Comparison of Ross` capillary barrier diversion formula with detailed numerical simulations

Description: Ross developed an analytical relationship to calculate the diversion length of a tilted fine-over-coarse capillary barrier. Oldenburg and Pruess compared simulation results using upstream and harmonic weighting to the diversion length predicted by Ross formula with mixed results; the qualitative agreement is reasonable but the quantitative comparison is poor, especially for upstream weighting. The proximity of the water table to the fine-coarse interface at breakthrough is a possible reason for the poor agreement. In the present study, the Oldenburg and Pruess problem is extended to address the water table issue. When the water table is sufficiently far away from the interface at breakthrough, good qualitative and quantitative agreement is obtained using upstream weighting.

RCRA Groundwater Quality Assessment Report for Waste Management Area S-SX (November 1997 through April 2000)

Description: This report updates a continuing groundwater quality assessment for single-shell tank Waste Management Area S-SX at the Hanford Site. This report covers November 1997 through April 2000. Major new findings include the following: groundwater contamination continues to persist in both the northern half of the Waste Management Area as well as the southern half; evaluation of changes in water table elevations indicates a gradual shift in the direction of groundwater flow from the southeast to a more easterly direction; discrete depth sampling suggests mobile tank waste contaminants are at the very top of the aquifer in downgradient wells along the southeast side of the SX tank farm.

The Bladon Lysimeter: An Innovative Environmental Characterization Technology

Description: Chemical analysis of groundwater samples is the baseline method of characterizing and monitoring groundwater contamination in the vadose (unsaturated) zone at most waste sites. Contamination moving from the surface to the water table passes through an unsaturated zone that can range in thickness from a few inches to hundreds of feet at a give site. Lysimeters are samplers that are designed to apply suction to the subsurface and are typically used to collect groundwater in the unsaturated zone.

In situ bioremediation using horizontal wells

Description: In Situ Bioremediation (ISB), which is the term used in this report for Gaseous Nutrient Injection for In Situ Bioremediation, remediates soils and ground water contaminated with volatile organic compounds (VOCs) both above and below the water table. ISB involves injection of air and nutrients (sparging and biostimulation) into the ground water and vacuum extraction to remove .VOCs from the vadose zone concomitant with biodegradation of VOCs. The innovation is in the combination of 3 emerging technologies, air stripping, horizontal wells, and bioremediation via gaseous nutrient injection with a baseline technology, soil vapor extraction, to produce a more efficient in situ remediation system.

Seismic reflection imaging at a Shallow Site

Description: The objective of our studies was to determine the best seismic method to image these sediments, between the water table at 3 m depth to the basement at 35 m depth. Good cross-correlation between well logs and the seismic data was also desirable, and would facilitate the tracking of known lithological units away from the wells. For instance, known aquifer control boundaries may then be mapped out over the boundaries, and may be used in a joint inversion with reflectivity data and other non-seismic geophysical data to produce a 3-D image containing quantitative physical properties of the target area.

Innovative technology summary report: six phase soil heating

Description: Six Phase Soil Heating (SPSH) was developed to remediate soils contaminated with volatile and semi-volatile organic compounds. SPSH is designed to enhance the removal of contaminants from the subsurface during soil vapor extraction. The innovation combines an emerging technology, that of six-phase electrical heating, with a baseline technology, soil vapor extraction, to produce a more efficient in situ remediation system for difficult soil and/or contaminant applications. SPSH is especially suited to sites where contaminants are tightly bound to clays and are thus difficult to remove using soil vapor extraction alone. Target zones to be treated would most likely be above the water table, but a thicker treatment zone could be addressed by hydraulically lowering the water table with pumping wells.

Innovative technology summary report: in situ air stripping using horizontal wells

Description: In situ air stripping (ISAS) technology was developed to remediate soils and ground water contaminated with volatile organic compounds (VOCs) both above and below the water table. ISAS employs horizontal wells to inject (sparge) air into the ground water and vacuum extract VOCs from vadose zone soils. The innovation is creation of a system that combines two somewhat innovative technologies, air sparging and horizontal wells, with a baseline technology, soil vapor extraction, to produce a more efficient in situ remediation system.

Self-potential, soil co2 flux, and temperature on masaya volcano, nicaragua

Description: We investigate the spatial relationship between self-potential (SP), soil CO{sub 2} flux, and temperature and the mechanisms that produce SP anomalies on the flanks of Masaya volcano, Nicaragua. We measured SP, soil CO{sub 2} fluxes (<1 to 5.0 x 10{sup 4} g m{sup -2} d{sup -1}), and temperatures (26 to 80 C) within an area surrounding a normal fault, adjacent to Comalito cinder cone (2002-2003). These variables are well spatially correlated. Wavelengths of SP anomalies are {le}100 m, and high horizontal SP gradients flank the region of elevated flux and temperature. Carbon isotopic compositions of soil CO{sub 2} ({delta}{sup 13}C = -3.3 to -1.1{per_thousand}) indicate a deep gas origin. Given the presence of a deep water table (100 to 150 m), high gas flow rates, and subsurface temperatures above liquid boiling points, we suggest that rapid fluid disruption is primarily responsible for positive SP anomalies here. Concurrent measurement of SP, soil CO{sub 2} flux, and temperature may be a useful tool to monitor intrusive activity.

An Updated Regional Water Table of the Savannah River Site and Related Coverages

Description: A new regional-scale map of the water table configuration beneath the Savannah River Site and its surrounding area has been developed. This map is an update to the regional watertable map presented in1998. While similar methods were used to develop the updated coverages, increased accuracy was achieved due to several factors, including: (a) more data (new wells and additional measurements), (b) use of median versus mean water levels for water table contour development, (c) culling erroneous values from the data records, and (d) eliminating wells discovered to not reflect natural conditions.
