12
Use Emergency Planning
The Nuclear Response and Environmental
Surveillance section uses Emergency Planning Zone
and Grid Maps that combine spatial data from the
Power Stations, SCDHEC and other sources to
provide field teams and EOC staff with maps for
navigation and evaluation of plume modeling
results. The various sites also now use these
DHEC maps for their drills.
13
Use Identification of Site Extents
These maps produced for the Resource Conservation
and Recovery Act (RCRA) Program use a combination
of historical and recent aerial photographs and
current GIS layers to help define the past and
current extent of solid waste management units
(SWMU) at sites such as the Naval Weapon Station
and the Marine Corp Air Station. In some
instances, new SWMUs have been identified by
photointerpretation of historic aerial
photographs of the sites.
14
Use Public Hearings / Outreach
For a Division of Site Assessment and Remediation
project , a combination of contractor-provided
modeling data and CAD files, in conjunction with
aerial photography, was used to produce site maps
displayed during public awareness meetings.
15
Use Permitting
This map was produced for the Division of Mining
and Solid Waste Management to aid in the
permitting of new landfills and analyze the
coverage areas of existing landfills. The
underlying data was created using coordinates
supplied on permits and through GPS point
collection by Solid Waste staff. GIS was used to
determine areas of overlap and areas not covered
by existing landfills.
16
Use Modeling
GIS software modeling capabilities were used in
this Underground Storage Tank project to evaluate
the relationship of petroleum products and
groundwater in Marion, South Carolina. The data
layers included well information,
contractor-supplied CAD files and GIS baselayers.
17
Use Superfund Initiatives
This Site Assessment and Remediation Division
project involved using GPS collected sample sites
in combination with other GIS layers such as
scanned USGS topographic quadrangle maps, aerials
photos, endangered species GIS layers, streams,
surface water intakes and roads to produce maps
in support of EPA and Superfund initiatives.
Other projects for SAR have used SCDHEC GIS to
estimate population around sites and determine
what other sources of contamination may be
present in the immediate area.
18
Use Surface Water Classifications
19
Use Resource Protection
20
Use Non-point Sources
Non Point Source (NPS) - Potential Activities
Impacting Shellfish Harvest Area Closures
ArcPad Application Builder used to develop NPS
form for entering sites. During routine
monitoring, DHEC Shellfish Officers will GPS the
NPS sites, documenting the activity type. If
the NPS activity is correctable, the application
is designed to send a notification to the central
office to conduct an investigation.
21
Use Contaminant Evaluation
22
Use Community Structure Impacts
The Effects of Land Use On Aquatic
Macroinvertebrate Community Structure
Abstract The purpose of this study was to
determine if landuse within a watershed affected
aquatic macroinvertebrate communities. Aquatic
macroinvertebrates are good indicators of stream
quality, meaning that the physical and chemical
conditions of a stream affect them. The
biological integrity of a stream ecosystem
depends critically on human activities that
affect landuse. The goal of this study was to
determine whether landuse was an effective
predictor of stream integrity. Nine sites in
three different water basins were surveyed by
using kick nets and D-frame nets to collect
aquatic macroinvertebrate samples. The geographic
information system (GIS) program ArcView Version
3.1 was used to calculate the percentages of
agriculture, urbanization, and forest within the
nine watersheds associated with the nine
streams. The range of conditions among the 9
streams varied from poor to excellent based on
the Save Our Streams Index (SOS) (an Izaak
Walton League protocol). The stream biotic
integrity was negatively correlated with the
extent of urbanization (r2 0.59, p 0.016) and
positively correlated with the extent of forest
(r2 0.77, p 0.002). Within the watersheds,
there was no significant relationship between
percent agriculture and biotic integrity (r2
0.15, p 0.31).
Results The water quality ratings were
negatively correlated with the extent of
urbanization (r2 0.59, p 0.016)(Fig. 2) and
positively correlated with the extent of forest
land use (r2 0.77, p 0.002) (Fig. 3). Within
the watersheds, there was no significant
relationship between percent agriculture and
water quality ratings (r2 0.15, p 0.31)(Fig.
4).
Discussion The results of this study were
similar to those found by Glover and Eidson
(1997). They also found a negative correlation
between urbanization and their bioclassification
scores, a positive correlation between forest
land use and their bioclassification scores, and
no relationship between percent agriculture and
bioclassification scores. This suggests that the
Izaak Walton League Save Our Stream protocols
used in this study by high school students
compared favorably with more rigorous techniques
used by state biologists i South Carolina. This
is further supported by work of Canada et. al.
(2000). Urbanization has a profound impact on
water bodies and the pollutants that the rain
wash from smoggy air and dirty streets is just
one small part of the story. The moment we start
covering up the natural landscape with asphalt
and concrete we start to change watershed
hydrology. While urbanization is a growing
problem throughout the world, there are different
steps that can be taken to help reduce impacts on
streams and their aquatic life. These steps are
referred to as best management practices (BMPs)
and include the following nonstructural BMPs,
wet pond detention basins, dry pond detention
basins, artificial wetlands, water quality inlets
and oil and grease trap catch basins,
infiltration practices, vegetative practices, and
erosion and sediment control practices during
construction (Terrene Institute 1996).
Materials and Methods Nine stream locations
were chosen as study sites (Fig. 1,Table 1). The
Heathwood Hall Environmental Science Group
conducted all sampling. This group consisted of
12 Upper School students in grades 10 through 12
(Canada et. al. 2000). Sites were chosen that
ranged from little or no natural vegetation
within the watershed to watersheds, which were
relatively undeveloped. At each site using
D-frame nets and kick nets all available
habitats were sampled. Habitat types included
riffles, undercut root banks, mature leaf
packs, and stick-ups. In addition visual
observations were conducted of large rocks and
woody debris. The macroinvertebrates, which were
collected, were placed in white plastic pans.
Each organism was identified to a specific
taxonomic category according to the Izaak Walton
League protocol. This protocol stratifies
organisms into three groups sensitive, some-what
sensitive, and tolerant. While in the field, a
total index value was calculated for each site
and converted to a water quality rating of poor,
fair, good, or excellent. The geographic
information system (GIS) program ArcView Version
3.1 was used to calculate the percentage of
agriculture, urbanization, and forest within the
nine watersheds associated with the nine streams.
Land classifications followed a hierarchical
system of land use categories, which were
aggregated into three broad categories of urban,
agricultural, and forested.
