GENERAL DESCRIPTION:
The Source Water Assessment and Protection Program (SWAPP) is a statewide layer that attempts to identify potential contamination sources (PCS) to the ground water used by Public Water System (PWS) wells. Assessment areas were created for each PWS well to identify the PCSs.

USER NOTES:
This data is provided 'as is'. GeoPlan relied on the integrity
of the original data layer's topology
The Public Water System Database is constantly updated.  The assessment 
areas will not include recent updates.  Assessment areas for new wells will not 
exist.  Assessment areas for wells which have a recent location correction will 
not show the correction.  Assessment areas for wells that have been shut down 
will still be in the database.  Changes in well identification will not be shown in 
the assessment area data.
GeoPlan relied on the integrity of the attribute information within
the original data.

Assessment areas were created for each Public Water Supply (PWS) 
well to identify potential contamination sources.  PWS wells are divided 
into three categories:  1) noncommunity, 2) community serving populations 
less than 1,000 persons and 3) community serving populations greater than 
or equal to 1,000 persons.

Assessment areas for noncommunity wells are a 500 ft radius buffer of 
the well.

Assessment areas for community wells serving populations < 1,000 persons 
are a 1,000 foot radius buffer of the well.  

Assessment areas for community wells serving populations >= 1,000 persons 
are a 1,000 foot radius buffer of the well plus a five year ground water travel 
time.

The basis of the assessment areas is the public water system 
wells.  If the well locations are altered, the linkage could be 
compromised. The accuracy of the protection areas are also 
affected by the accuracy of the Potable Water Supply Wells layer.

The Florida Geographic Data Library is a collection of Geospatial Data
compiled by the University of Florida GeoPlan Center with support from
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
about the currentness of the data and suggests that data users check
with the data source to see if more recent versions of the data exist.

Furthermore, the GIS data available in the FGDL are provided 'as is'.

provided by the data sources. The University of Florida GeoPlan Center

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:
The Public Water System Well point data set was divided into two sets 
based on system type, community and non-community.  A 500 ft buffer 
was created around the non-community points.  A 1000 ft buffer was 
created around the community wells.  The buffers were not dissolved, 
but kept as independent areas for each well point.  Community wells with 
a population served greater than 1000 had a 5 year ground water travel 
time calculated.  These travel times were converted to polygons and merged 
with the corresponding 1000 ft buffer into a single polygon for each well.

GeoPlan downloaded this data from The Florida Department of Environmental Protection (http://www.dep.state.fl.us/gis/datadir.asp) in March of 2009. When downloaded the data was in the following projection: Albers, datum: NAD83 HARN, units: meters. Records that were found to be located in the Atlantic Ocean or Gulf were deleted. The following WELL_ID's were deleted: 40577, 29514, 30737, 31180, 32298, 32317, 32357 37078, 33619, 38937, 42698, 42699, 42701, 44380, 42858, 5477, 24472 - Added DESCRIPT field based on PWS_NAME - Added FGDLAQDATE based on date downloaded from source. - Deleted field PWS_ID - Renamed dataset swapp_jun08 from SOURCE_WATER_PROTECTION_AREAS Process Date: 20090303
