Description:

Abstract:

Ground-water contribution classes is one of 6 data sets updated for the
North Carolina Public Water Supply, Source Water Assessment Program.
These data are used to rate the susceptibility of public water supplies
in North Carolina to contamination.

The original dataset was produced in 2000. This version is updated to
reflect new data sources.

This data set represents the influence that ground-water has on surface
waters. This area of influence has been defined as the area within 1000
meters of any stream or waterbody in North Carolina. The portion of
surface water derived from ground water influences surface-water
quantity and quality.

The ratings for the susceptibility to contamination of the unsaturated
zone were applied within the area of influence. High ratings for
ground-water contribution indicate a higher inherent vulnerability
to the unsaturated zone, and since it contributes to the rating of
watershed characteristics, also indicates a higher vulnerability for
watersheds.

Purpose:

This data set is to be used in a hydrologic analysis with other
data sets to rate the unsaturated zone for public ground-water
supplies and watershed characteristics for public surface-water
supplies in North Carolina.

For ground-water supplies, the factors used to rate susceptibility to
contamination include vertical hydraulic conductance, land-surface slope,
land cover, and land use.  The selected factors used to devise ratings for
surface-water supplies' susceptibility to contamination are average annual
precipitation, land-surface slope, land cover, land use, and ground-water
contribution.

Supplemental information:

The 1996 Amendments to the Safe Drinking Water Act require that each state prepare a source-water assessment for all public water supplies. States are required to (1) delineate source areas supplying wells and surface-water intakes, (2) inventory potential contaminant sources within the delineated source areas, and (3) determine the susceptibility of wells or intakes to the inventoried potential contaminant sources.

In North Carolina, the lead agency charged with this task is the Public Water Supply Section (PWSS) of the Division of Environmental Health, Department of Environment and Natural Resources (DENR). North Carolina's Source Water Assessment Program (SWAP) provides assessments of each public drinking water intake in North Carolina. These assessments provide a relative susceptibility rating calculated using state-wide data.

The U.S. Geological Survey (USGS) cooperated with the PWSS to provide components of the inherent vulnerability rating that was used with the contaminant rating to determine the overall susceptibility rating of source water supplies. To assist the PWSS with rating ground water inherent vulnerability, the USGS compiled the unsaturated zone rating based on the following characteristics: vertical hydraulic conductance, depth to water, land surface slope, land use and land cover. The watershed characteristic rating includes average annual precipitation, land surface slope, land use, land cover and groundwater contribution.

The SWAP program has planned for updates to the initial ratings as conditions change and new data sources become available. The initial data used to calculate the unsaturated zone ratings and watershed characteristics ratings were compiled from sources from the late 1990's. Critical data layers have been updated since the ratings were calculated. These improved data layers need to be used in the ongoing update of the susceptibility ratings.

Overlay and index methods for rating susceptibility to contamination
of the unsaturated zone for ground-water suppplies, and watershed
characteristics for surface-water supplies were derived for use
by the State of North Carolina in assessing more than 11,000 public
water-supply wells and approximately 245 public surface-water intakes.
Factors that influence the inherent vulnerability of ground water and
surface water were selected and assigned ratings on a scale of 1 to 10.
These factors were then assigned weight to reflect their relative influence
on inherent vulnerability and the reliability of the data.  The
values for each factor were obtained from geographic information
system (GIS) data layers that were transformed into ARC/INFO
raster data sets known as grids. These raster data sets have
30-meter by 30-meter cells, and each cell is assigned a weighted-
factor value.

Limitations --

The overlay and index methods of unsaturated zone and watershed
characteristics ratings are broad-stroke methods that assess
vulnerability on the basis of expert opinion. The methods aslo have
limitations in the age and scale of the hydrologic and geographic
data. But the most significant limitation of the methods used
is that no statistical confirmation of the results have been
performed.

GROUND-WATER CONTRIBUTION-

Management of surface-water resources has traditionally focused on
surface water alone.  However, surface water and ground water
compose one system.  Streamflows are partly derived from underlying
aquifers, particularly when the aquifer's upper boundary is the
water table.  During dry conditions, the portion of streamflow
coming from ground water is known as base flow, sometimes referred
to as sustained fair-weather flow.  In periods of extended dry
conditions, flows observed in the stream channel consist only of
base flow (and non-natural stream inputs such as wastewater discharge).
During storm events, the portion of streamflow coming from ground water
is known as subsurface stormflow (Freeze and Cherry, 1979; Winter
and others, 1998).

The ground water contribution factor is included in the assessment
of watershed characteristics to address the influence that ground
water has on surface-water quantity and quality. In this study,
ground-water contribution is a factor in areas within about 1,000
feet of streams.  By restricting ground-water contribution to an
area of about 1,000 feet on either side of streams, this factor
emphasizes subsurface stormflow and local ground-water flow.
Ground-water contribution is not considered to have originated
outside of this buffer, though this component of ground-water
flow is of increasing importance in a stream experiencing low-flow
conditions.

Inclusion of a ground-water contribution factor addresses the
influence that ground water has on the vulnerability of surface
waters to contaminant transport from ground water discharge.

This metadata can not fully document the methods used in the
project to assess ground-water contribution to surface waters.
See Eimers and others (1999) for a detailed description of the methods.
The unsaturated zone ratings are applied to an area about 1,000
feet on either side of streams.  Ground-water contribution ratings
for these areas in watersheds upstream from surface-water intakes
are calculated exactly as for unsaturated zone ratings, but to
normalize these values from 1 to 10 the unsaturated zone rating
for each contributing cell is divided by 10.  In areas outside of the
1000 foot buffer zone, the ground-water contribution is zero.

Processing Steps-

The ground-water contribution component was derived from applying
the unsaturated zone ratings within a 1,000 feet (304.80061 meter)
area around streams and waterbodies in the National Hydrographic
Dataset (NHD) distributed by the U.S. Geological Survey and the U.S.
Environmental Protection Agency.

First, all stream segments that were assigned a reach were
extracted from the NHD. The reaches create a dendritic network
representing the centerlines of any lakes or double-sided streams.
Ocean or estuary HU's were processed separately to remove ocean
shoreline reaches.

305 meter polygons were drawn around either side of all
streams using the Arc/Info "BUFFER" command. The streams were
processed within 8-digit hydrologic cataloging unit areas.
Occasionally the buffered areas extended over the ridgelines
defined by the cataloging units. The areas that extended over
the cataloging unit boundaries were removed.

Next, the buffered streams were adjusted to include waterbodies
that overlapped the buffered stream areas that were not considered
"SEA" polygons. This insured that the middle of lakes wider than
305 meters are included in the analysis of ground-water contribution.

Finally, the unsaturated-zone rating grid was applied to the
buffered zones within North Carolina.
