USER NOTES:







GeoPlan relied on the integrity of the attribute information within the original data.












The presence of ground water contaminants is indicated by a number 1 for each 
of the 42 contaminants listed in the attribute table.  The DEP quad number is referenced 
by the item quad#, the delineated area is referenced by item zoneid, the water
management district is referenced by the item wmd, and the quad name is 
listed in item quad-name.













A note concerning data scale:

Scale is an important factor in data usage. Certain scale 
datasetsare not suitable for some project, analysis, or
modelling 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.

1:250000 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 analyses. Every 
effort has been made to supply the user with data 
documentation. For additional information, see the 
References sectionand the Data Source Contact section of 
this documentation. For more information regarding scale 
and accuracy, see our web pages at:

DATA LINEAGE SUMMARY: 









Data on locations of contaminated ground water sites 
(those not meeting primary drinking water standards in 
regard to any of 42 ground water contaminants as described 
by DEP rule 17-550) came from the Health and Rehabilitative 
Services database, DEP ground water site investigations, state 
and federal clean up sites, and modeled ground water contaminent 
plumes.  For HRS EDB wells, USGS 7.5" quadrangles were 
were overlayed with 100 meter UTM grids.  The location of 
each contaminated well was digitized to the nearest 100 
meters in the appropriate UTM projection.  These points were 
then buffered by 1000-2000 feet.  Site maps and plume 
models were transfered to 7.5" quads and digitized on a 
Calcomp 9100 digitizer using ARC/INFO.

The individual quad coverages of buffered points were 
projected from UTM to Lambert using ARC/INFO for VMS 
on a VAX.  The coverages were then mapjoined, dissolved, 
projected to Albers Equal Area Conic, and exported.  The 
exported coverages were ftp'd to a DEC/ALPHA UNIX system, 
imported using ARC/INFO 6.1.2 and inserted into the quad library.
Process Date: 1990


In Spring '97 the data was converted from NAD27 to 
HPGN using the projection command within ARC/INFO 
version 7.0.4.
Process Date: 19970000


In Spring, 1999, the shapefile of this dataset was inserted 
in Spatial Database Engine (SDE 3.0.2).
Process Date: 19990000


GeoPlan downloaded this dataset from the Florida 
Department of Environmental Protection website 
(http://www.dep.state.fl.us/water/data.htm) in 2004. 
The data was downloaded as a shapefile and was 
in the following projection: FGDL Albers HPGN.

- Added a DESCRIPT field based on COUNTY.
