Start
date: 7/1/2000
|
End
date: 6/30/2003
|
|
Executive Summary
The major emphasis of the Nonpoint Source Education for Municipal Officials (NEMO) program is to help local government officials better understand the complex relationship between land use, urban growth and water quality. It is the goal of this assistance is to inform municipal officials so they will make better-educated and informed decisions that help improve water quality and control nonpoint source pollution (NPS). To guide local decision makers, NEMO outlines a three-tiered strategy of natural resource-based planning, site design, and the use of best management practices to address their land use and to deal with NPS pollution. The role of ESRI-USC in this program is to furnish localized analysis of each presentation area, illustrating the present day effects of NPS and projecting how future growth may affect NPS pollution within the area.

Seismic DNAPL Detection at 200 West Area, USDOE Hanford Site
|
|
|
Start
date: 10/1/1998
|
End
date: 12/31/2002
|
|
Executive Summary
The goal of the seismic reflection research was to determine whether high concentrations of DNAPL (CCl4) in the subsurface at 200 West Area could give rise to seismic amplitude anomalies. If such amplitude anomalies exist, the distribution can be mapped and calibrated versus borehole measurements. A secondary goal was to map the subsurface geology and delineate probable preferential pathways for DNAPL transport.

Application of Geophysical Techniques to Site Characterization and 3D Visualization
|
|
|
Start
date: 1/1/1998
|
End
date: 12/31/2002
|
|
Executive Summary
ESRI is providing geophysical expertise and oversight to Argonne National Laboratory's (ANL) QuickSiteSM investigations of subsurface DNAPL contamination at former USDA Commodity Credit Corporation grain storage sites in the Midwest. At these sites materials used to fumigate grain decades ago are the cause of DNAPL contamination. The DNAPL, commonly carbon tetrachloride, migrates through the overlying glacial sediments and accumulates on clay layers and atop the bedrock surface at depths to 100 feet. Insofar as many CCC sites were located within or near town limits, the potential for contamination of public drinking supplies is high. Because the geological characteristics of the glacial overburden are laterally and vertically variable, geophysical methods are needed to detect and map buried channels and other heterogeneities that might influence contaminant transport.

Optimizing the Design Features of the Funnel and Gate Groundwater Remediation Technology
|
|
|
Start
date: 3/1/1998
|
End
date: 3/31/2002
|
|
Executive Summary
The funnel and gate groundwater remediation technology has received increased attention and application as an in situ alternative to the typical pump and treat system. Understanding the effects of heterogeneity on system performance can be the difference between a successful remediation project and a project that fails to meet its cleanup goals.
In an attempt to characterize and quantify the effects of heterogeneity on funnel and gate system performance, a numerical modeling study of 15 simulated heterogeneous flow domains was conducted. Each realization was tested to determine if the predicted capture width met the capture width expected for a homogeneous flow domain with the same bulk properties. This study revealed that the capture width of the funnel and gate system varied significantly with the level of heterogeneity of the aquifer.
Two possible remedies were investigated for bringing systems with less than acceptable capture widths to acceptable levels of performance. First, it was determined that enlarging the funnel and gate via a factor of safety applied to the design capture width could compensate for the capture width variation in the heterogeneous flow domains. In addition, it was shown that the use of a pumping well downstream of the funnel and gate could compensate for the effects of aquifer heterogeneity on the funnel and gate capture width. However, if a pumping well is placed downstream of the funnel and gate to control the hydraulic gradient through the gate, consideration should be given to the gate residence time in relation to the geochemistry of the contaminant removal or destruction process in the gate.

End
date: 12/1/1999
|
|
Executive Summary
A request for project work by an independent oil company allowed ESRI to add significant information to its already significant database of information on the Major Oil and Gas Fields of the world
We have added to the information base cross-sections, maps, and other images of the worlds 80 largest oil and gas fields. Each of these particular fields consist of reserves >6.0 billion BOE.
The images are in an electronic format as “jpg” files. Petroleum Abstracts in Tulsa aided in the data search and references in several languages were obtained from all over the world to complete this work. These images are presently unlinked to the main database but plans for the future consist of linking the maps with the appropriate reservoir or other information category.

GIS Hydrogeologic Database Demo
|
|
|
Start
date: 9/1/1994
|
End
date: 9/30/1998
|
|
Executive Summary
The purpose of this project was to develop and implement a multi-purpose geographic information system (GIS) for the storage, retrieval, and analysis of geologic data at the Savannah River Site (SRS). At the completion of this project, personnel at SRS now possess a single system capable of furnishing a variety of data sets available for specific areas, sites, wells, and locations within SRS. This GIS data base should decrease time expenditures by site and contractor personnel for researching existing site-specific data. In addition, the GIS data base can reduce redundancy of data collection by separate researchers by making data readily accessible between departments and contractors. Data within the GIS data base include not only new information obtained from projects occuring coincidently with the duration of the GIS/Database Entry project (1994 to 1997) but also a significant portion of the enormous volume of data already generated and stored in separate facilities and departments at SRS.

Mississippi Salt Basin Seismic Interpretations - Phase II
|
|
|
Start
date: 5/1/1997
|
End
date: 1/1/1998
|
|
Executive Summary
In a five county area south and east of the Jackson Dome 27 drilling leads were generated using the premises developed in the Phase 1 portion of the project. Both regional and local seismic data was used and sedimentation history of the area was interpreted using those concepts. Although the focus of the work was confined to the pre-Selma/ post-Smackover, leads were also noted in the Smackover.It is probable that we have previously mapped prospects in the area and subsequently drilled in locations that are offset to the crest of major features.
