DS926 Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system in Florida and parts of Georgia, Alabama, and South Carolina -- Polygon regions depicting saline areas of the Lower Floridan aquifer

Digital surfaces and thicknesses of selected hydrogeologic units of the Floridan aquifer system were developed to define an updated hydrogeologic framework as part of the U.S. Geological Survey Groundwater Resources Program. This feature class contains polygons depicting areas of this unit estimated to have greater than 10,000 mg/L of TDS.

作为美国地质调查局（U.S. Geological Survey）地下水资源计划（Groundwater Resources Program）的组成部分，本数据集针对佛罗里达含水层系统（Floridan aquifer system）中的选定水文地质单元，生成了其数字地表与厚度数据，用于确立更新后的水文地质框架。本要素类（feature class）包含了经估算总溶解固体（Total Dissolved Solids，TDS）浓度高于10000 mg/L的对应单元区域的面要素多边形。
