Baseline Water Quality Studies for 3 SC watersheds
|
|
|
Start date: 11/1/2005
|
End
date:
|
|
Overview
ESRI-SC developed a baseline water quality assessment for the
South Fork Edisto, Black, Lynches, and Saluda River
watersheds. This baseline assessment, basied on historic
water quality data from SCDHEC serves as a quick reference
of water quality statistics for 1999-2004 and provides
enough information for future users of the data to rapidly
calculate confidence intervals that are relevant to the data
and their relation to SCDHEC water quality criteria.
We
conducted additional analyses of some indicators (Total
Nitrogen (TN), Total Phosphorus (TP) and fecal coliform
(FC)) in relation to upstream indicators, e.g., land use,
wastewater treatment plants and livestock operations, and
how they influence water quality. We found that the most
significant predictor of high TN and TP is the presence of a
wastewater treatment plant (WWTP) 15 miles upstream or
less. The most significant predictor of fecal coliforms is
percentage urban area upstream of a WQMS. This factor is
also a significant (but secondary) predictor of TN.
Contrary to expectations, we were unable to find a
significant adverse relationship between livestock
operations intensity and water quality (specifically TN, TP
and FC). We concluded that, while it is clear from the
literature that certain agricultural operations can
adversely affect water quality, these agricultural effects
are almost invariably overwhelmed by nearby upstream urban
point and non-point sources in our study area.

Overview
The program of work between USC’s Earth Sciences and Resources Institute (ESRI-SC) and the NRCS of South Carolina began in 1998. The intention was that
ESRI-SC would assist the NRCS in the development and implementation of a GIS-based Decision Support System (DSS) to promote the sound planning of conservation systems, especially those concerning the utilization of animal manure. The use of spatial analysis components within the GIS model would be to develop a map showing the suitability of lands for the siting of buildings, lagoons and land application of manure. The data to be used in the spatial analysis component would include underlying environmental data (including surface water quality, leachability and soil erosion indices), regulatory requirements and economic constraints associated with hauling costs of the manure.

date: 9/21/2003
|
|
Overview
This
study is executing a comprehensive aquifer vulnerability and
contamination potential assessment (VCPA) at the Marine Corps Air
Station, Beaufort (MCAS) with the results of the assessment integrated
into the installation’s Geographic Information System (GIS). The
objective of the integration, which merges environmental and
infrastructure GIS, is to facilitate the development of risk management
plans, fulfill regulatory reporting requirements, and aid in answering
public enquiries concerning environmental issues within and surrounding
the MCAS. This project correlates pertinent environmental data already
held by the MCAS and new information collected by this study to create
a comprehensive, site-wide model of the groundwater, surface water and
hydrogeology of the air base.

End
date: 6/30/2003
|
|
Overview
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-SC 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
|
|
Overview
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.

End
date: 12/31/2002
|
|
Overview
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.

Overview
As
GIS software is becoming widely used in a variety of applications, the
need to provide confidentiality of data used by GIS arises. The faculty
of the Earth Sciences and Resources Institute and the Department of
Computer Science and Engineering at the University of South Carolina
collaborated to study information confidentiality issues in GIS context
and to define an access control model for a multi-user geodatabase
within an enterprise-level GIS environment. This project discusses our
findings and difficulties during the implementation of the model to
enforce access control in spatial databases created with ArcGIS 8.1,
ArcSDE 8.1 and MS SQL Server 2000.

Optimizing the Design Features of the Funnel and Gate Groundwater Remediation Technology
|
|
|
Start
date: 3/1/1998
|
End
date: 3/31/2002
|
|
Overview
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.

|
Overview
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.

Overview
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.
