Name: DRASTIC Coverage for the Floridan Aquifer System
Display Field: SETTING
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This coverage contains statewide DRASTIC data for the Floridan Aquifer System. 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 introduced on the ground's surface.
Name: DRASTIC Coverage for the Intermediate Aquifer System
Display Field: SETTING
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This coverage contains statewide DRASTIC data for the Intermediate Aquifer System. 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 introduced on the ground's surface.
Name: DRASTIC Coverage for the Surficial Aquifer System
Display Field: SETTING
Type: Feature Layer
Geometry Type: esriGeometryPolygon
Description: This coverage contains statewide DRASTIC data for the Surficial Aquifer System. 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 introduced on the ground's surface.
Description: Generalized recharge to and discharge from the Floridan Aquifer System. This layer covers the entire state of Florida. Aquifers are underground layers of rock and sand that hold water. These layers are made up of loosely packed sediments and layers of calcium-rich limestone and dolomite. In Florida, most of the population depends on the Upper Floridan aquifer for their drinking water. The Upper Floridan aquifer, which is the largest aquifer in the state, holds the ground water like a sponge. Holes in the rock that makes up the aquifer allow the water to move freely through it. The Upper Floridan aquifer stretches for 100,000 square miles beneath Florida and parts of Alabama, Georgia and South Carolina.
Description: This map layer contains the shallowest principal aquifers of the state of Florida portrayed as polygons. The map layer was developed as part of the effort to produce the series "Ground Water Atlas of the United States". The published maps contain base and cultural features not included in these data. This is a replacement for the July 1998 map layer called Principal Aquifers of the 48 Conterminous United States created by the U.S. geological Survey.
