Florida Department of Environmental Protection 19990310 shapefile http://www.dep.state.fl.us aqpsfl01 This dataset contains countywide DRASTIC data for the Intermediate Aquifer System recalibrated for pesticide use. DRASTIC is a system developed jointly by the U.S. Environmental Protection Agency (USEPA) and the National Water Well Association (NWWA) to map potential aquifer vulnerability to pollution (in this case, resulting from pesticide use) introduced on the ground's surface. DRASTIC is a system developed jointly by the U.S. Environmental Protection Agency (USEPA) and the National Water Well Association (NWWA) to map potential aquifer vulnerability. The methodology utilizes existing hydrogeological information to produce color-coded maps which display areas that are more or less likely to be affected by pollution introduced on the ground's surface. These maps depict areas which are more or less sensitive to land use changes which may affect ground water quality. Drastic maps are composites made up of eight individually mapped hydrogeological parameters. Seven of these parameters (depth to water - Dw, net recharge - Nr, aquifer media - Am, soil media - Sm, topography - T, impact of the vadose zone - Iv and hydraulic conductivity - Hc) are used to derive the DRASTIC summary index score. The eighth, hydrogeologic setting, is useful for general map interpretation but, it is not included in the summary index. Pesticide DRASTIC is designed to be used where the activity of concern is the application of pesticides to an area. It represents a special case of the DRASTIC Index. The only way in which Pesticide DRASTIC differs from DRASTIC is in the assignment of relative weights for the seven DRASTIC factors. All other parts of the two indexes are identical; the ranges, ratings and instructions for use are the same. If the user is concerned with the ground water pollution potential of an area by pesticides, then the weights for Pesticide DRASTIC should be used. en 19990310 ground condition Complete Irregular -82.663385 -82.040266 29.939313 29.422649 529493.596923588939.710273602511.118596660672.275052 NONE Pesticide Pollution Florida Aquifer System Water Quality Planning NONE Florida Southeast United States Southeast U.S. NONE March 10,1999 1990s NONE THE DATA INCLUDED IN THIS APPLICATION ARE BASED ON INTERPRETATION OF AVAILABLE INFORMATION AND SHOULD NOT BE CONSTRUED AS LEGALLY BINDING. Scale is an important factor in data usage. Certain scale data sets are not suitable for some projects, analysis, or modeling purposes. Please be sure you are using the best available data. 1:24000 scale data sets 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 data sets are recommended for projects that are at the multi-county or regional level. 1:250000 scale data sets 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 section and the Data Source Contact section of this documentation.

Certain node/geometry and topology (GT)-polygon/chain relationships are collected or generated to satisfy topological requirements. Some of these requirements include: chains must begin and end at nodes, chains must connect to each other at nodes, chains do not extend through nodes, left and right GT-polygons are defined for each chain element and are consistent throughout the transfer, and the chains representing the limits of the file (neatline) are free of gaps. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data outside the enclosed region are ignored and all data crossing these geographically straight lines are clipped at the neatline. (Exception: During the QA/QC process all data is examined and if errors are found and corrections are possible, then data is corrected accordingly. This process is documented in the Process_Step.) Data within a specified tolerance of the neatline are snapped to the neatline. Neatline straightening aligns the digitized edges of the digital data with the generated neatline, that is, with the longitude/latitude lines in geographic coordinates. All internal polygons are tested for closure. Certain attributes and/or entities, e.g. closure line, convey data quality information. When information to be encoded in the subfield is known to be not applicable (undefined, not relevant), then the subfield is valued by a string of "9s"; and when the information to be encoded is relevant but unknown (or missing), then the subfield is valued by a string of "9s."
