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
