What Is GEMS?
A Web-based electronic data tool A Web-based dynamic mapping tool A system that allows stakeholders and the public
to access the large volume of environmental data collected as part of the U.S. Department of Energy (DOE) Office of Legacy Management’s (LM) long-term surveillance and maintenance activities at remediated sites

Background for GEMS
LM has responsibility for 87 sites as of the end of FY 2010 Sites that were formerly part of the nation’s nuclear
weapons production effort Sites are spread across 28 states and the
Commonwealth of Puerto Rico One of LM’s goals is to make legacy information
accessible

Geospatial Environmental Mapping System (GEMS) Created in 2002 and since then has evolved
and has been enhanced 58 LM sites have webpages in GEMS A custom-designed software application that provides
interactive mapping and environmental monitoring data for the managed sites

Objectives of GEMS
Communicate our monitoring information to our stakeholders and the public
Make data readily accessible about each LM site using the Internet at http://gems.LM.doe.gov
Implement a design that helps users easily visualize the relationships between data and geography
Allow users to map validated geochemical and hydrologic data from the LM Environmental Database

Major Components of GEMS
LM Environmental Database 4.3 million analytical chemistry results and field chemistry
measurements (as of October 19, 2010) 222,631 water level measurements 38 years of sampling data
Geospatial layers Aerial imagery for each site

Capabilities of GEMS
Interactive mapping Environmental data querying Applying reported data in many ways
Graph to identify trends Post as labels on the interactive map Add analyte concentration symbols to the map
Exporting data Export to a spreadsheet Export map to a PDF
