1. 2010 Long-Term Surveillance and Maintenance Conference GEMS Geospatial Environmental Mapping System Introduction and Live Demonstration Elaine Pilz and Keith Miller S.M. Stoller Corporation

2. 2010 Long-Term Surveillance and Maintenance Conference 2 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

3. 2010 Long-Term Surveillance and Maintenance Conference 3 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

4. 2010 Long-Term Surveillance and Maintenance Conference 4 LM Sites and Offices

5. 2010 Long-Term Surveillance and Maintenance Conference 5 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

6. 2010 Long-Term Surveillance and Maintenance Conference 6 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

7. 2010 Long-Term Surveillance and Maintenance Conference 7 Who Uses GEMS? Internal and external consumers Stakeholders and regulators (municipal, state, federal, tribal government, community groups) LM Site managers LM support contractor Site managers and site leads Scientists (geologists, hydrologists, researchers) Field staff (samplers, inspectors)

8. 2010 Long-Term Surveillance and Maintenance Conference 8 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

9. 2010 Long-Term Surveillance and Maintenance Conference 9 What Is in GEMS? Sampling locations Analytical chemistry data Groundwater depths and elevations Well construction and lithology logs Boundaries – site, disposal cell Base map entities (roads, fences, water bodies, rivers) Aerial imagery Topographic maps On-site photographs

10. 2010 Long-Term Surveillance and Maintenance Conference 10 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 See conference handout for more information
