National Sole Source Aquifer GIS Layer

Metadata Updated: Mar 31, 2016

This data set contains indexes and Esri shape files of boundaries of the designated sole source aquifers and related aquifer boundaries. Data provide a vector polygon GIS layer showing available materials representing extents at the land surface related to 78 designated Sole Source Aquifers (SSA) related to announcements in the Federal Register. GIS coverages for SSAs were obtained from EPA Regions 1, 2, 3, 4, 5, 6, 8, 9, and 10 for a baseline period in September of 2009. Each SSA polygon was checked against the Federal Register (FR) determination for that SSA. These coverages were appended, in order to create a national seamless coverage of SSAs. There are 89 GIS polygons for the Sole Source Aquifers, since in addition to a single SSA designated area polygons, some Regions have delineated GIS layers for streamflow zones, aquifer recharge areas, and other features at the land surface important for the SSA designations. GIS materials are not available at this time for the St. Joseph SSA in Indiana [53 FR 23682 (1988)].
