FLORIDA GEOGRAPHIC DATA LIBRARY DOCUMENTATION

TITLE: SOLE SOURCE AQUIFERS (SSA) IN THE STATE OF FLORIDA - 2011

Geodataset Name:       EPASSA_MAR11
Geodataset Type:       SHAPEFILE
Geodataset Feature:    Polygon
Feature Count:         3
GENERAL DESCRIPTION:
This data set contains indexes and Esri shape files of boundaries of the designated sole source aquifers and related aquifer boundaries. Data provide a vector polygon GIS layer showing available materials representing extents at the land surface related to 78 designated Sole Source Aquifers (SSA) related to announcements in the Federal Register. GIS coverages for SSAs were obtained from EPA Regions 1, 2, 3, 4, 5, 6, 8, 9, and 10 for a baseline period in September of 2009. Each SSA polygon was checked against the Federal Register (FR) determination for that SSA. These coverages were appended, in order to create a national seamless coverage of SSAs. There are 89 GIS polygons for the Sole Source Aquifers, since in addition to a single SSA designated area polygons, some Regions have delineated GIS layers for streamflow zones, aquifer recharge areas, and other features at the land surface important for the SSA designations. GIS materials are not available at this time for the St. Joseph SSA in Indiana [53 FR 23682 (1988)]. Additional information can be found at: https://edg.epa.gov/data/Public/OW/SSA_FR_notices_DWMA_Sept2009.Zip and https://edg.epa.gov/data/Public/OW/SSA_IDS_revd.xls This layer is an update to the FGDL layer SSAQUIFERS.shp

OBJECTID Internal feature number.

Shape Feature geometry.

SSA_ID Character string of the form "SSA_##" providing an identifier for the SSA designations. Since a given SSA can be located in more than a single county, a concatenation of the SSA_ID and the FIPS code are needed to establish a unique database key. Where polygons are provided for streamflow zones or other special features related to the SSA designations, the SSA_ID takes the form of SSA##a, SSA##b, or SSA##b. An example for an SSA designation involving 3 polygons areas is: SSA46a Edwards Aquifer II (Austin Area) SSA - Streamflow Source Zone 53 FR 20897 (1988); SSA46b Edwards Aquifer II (Austin Area) SSA -Recharge Zone 53 FR 20897 (1988); SSA46c Edwards Aquifer II (Austin Area) SSA - Artesian Zone 53 FR 20897 (1988).
SSA_001 thru SSA_078 = Related to time of designation


FR_ID Character string of the form "## FR #### (YYYY)" providing an identifier for the Federal Register citation for the SSA designations. Attribute_Definition_Source: Computed based on SSA_IDs developed for the Drinking Water Mapping Application and information in Federal Register Notices and GIS attributes in polygons supplied from the EPA Regions.
Character = Character value


AQUIFER Originally named SSA_NAME. The name of the SSA taken from the Federal Register and corresponding to a given SSA. The name will contain information related to the streamflow zone or other special features related to a specific polygon.
Character = Character value.

GeoPlan relied on the integrity of the attribute information within
the original data.
Additional detailed documentation for the SSA GIS coverages is available at 
https://edg.epa.gov/data/Public/ow/SSA_Documents.zip. GIS coverages for 
areas related to SSA designations were obtained from EPA Regions 1, 2, 3, 4, 5, 
6, 8, 9, and 10 for a baseline period of September, 2009. Each SSA polygon was 
checked against the Federal Register (FR) determination for that SSA. These 
coverages were appended, in order to create a national seamless coverage of 
SSA's. There are no official IDs for the SSAs. The SSA_IDs developed for the 
Drinking Water Mapping Application assign an ID (in the format SSA##) based on 
the Federal Register notices. The name of the SSA (SSA_NAME) and the Federal 
Register (FR_ID) are also provided to be able to identify each of the SSA 
polygons in this GIS layer. EPA provides background information on the SSA 
program at the following Internet address:

The SSA protection program is authorized by section 1424(e) of the Safe Drinking 
Water Act of 1974 (Public Law 93-523, 42 U.S.C. 300 et seq.). This program is 
designed to protect drinking water supplies in areas with few or no alternative 
sources to the ground water resource, and where, if contamination occurred, 
using an alternative source would be extremely expensive. EPA defines a sole or 
principal source aquifer as an aquifer that supplies at least 50 percent of the 
drinking water consumed in the area overlying the aquifer. These areas may have 
no alternative drinking water source(s) that could physically, legally and 
economically supply all those who depend on the aquifer for drinking water. For 
convenience, all designated sole or principal source aquifers are referred to as 
"sole source aquifers" (SSAs). The designation protects an area's ground water 
resource by requiring EPA to review certain proposed projects within the 
designated area. All proposed projects receiving federal funds are subject to 
review to ensure that they do not endanger the water source.

The Florida Geographic Data Library is a collection of Geospatial Data

the Florida Department of Transportation. GIS data available in FGDL is
collected from various state, federal, and other agencies (data sources)
who are data stewards, producers, or publishers. The data available in
FGDL may not be the most current version of the data offered by the
data source. University of Florida GeoPlan Center makes no guarantees

A note about data scale: 

Scale is an important factor in data usage.  Certain scale datasets
are not suitable for some project, analysis, or modeling purposes.
Please be sure you are using the best available data. 

1:24000 scale datasets are recommended for projects that are at the
county level.
1:24000 data should NOT be used for high accuracy base mapping such
as property parcel boundaries.
1:100000 scale datasets are recommended for projects that are at the
multi-county or regional level.
1:125000 scale datasets are recommended for projects that are at the
regional or state level or larger.

Vector datasets with no defined scale or accuracy should be
considered suspect. Make sure you are familiar with your data
before using it for projects or analysis. Every effort has been
made to supply the user with data documentation. For additional
information, see the References section and the Data Source Contact
section of this documentation. For more information regarding
scale and accuracy, see our webpage at:

DATA LINEAGE SUMMARY:
GIS coverages for SSA's were obtained from EPA Regions 1, 2, 3, 4, 5, 6, 8, 9, 
and 10 for a baseline period through September, 2009. GIS materials are not 
available at this time for the St. Joseph SSA in Indiana [53 FR 23682 (1988)]. 
Each SSA polygon was checked against the Federal Register (FR) determination 
for that SSA. In some instances, SSAs can extend across stateliness and can also
be included in more than a single EPA region. There are 84 GIS polygons for the 
Sole Source Aquifers, since in addition to a single SSA designated area polygons, 
some Regions have delineated GIS layers for streamflow zones, aquifer recharge 
areas, and other features at the land surface important for the SSA designations. 
The SSA_IDs, SSA names and Federal Register citations used for this national 
seamless SAA GIS layer include the following polygons: SSA01 Block Island
