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'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials. 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.

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. Process Date: 20081204 |
