Quality Data Asset includes all current and historical data on environmental quality with regard to the presence of radiological contamination of all kinds regulated by UMTRA, CERCLA, AEA, CWA, CAA.

An Excel database on NRC and Agreement State licensed mills providing status, locational/operational/restoration data, maps, and environmental reports including groundwater and air monitoring information. Developed for support of proposed regulatory revisions supporting UMTRCA and CAA-NESHAPs.

A GIS compiled locational database in Microsoft Access of ~15,000 mines with uranium occurrence or production, primarily in the western United States. The metadata was cooperatively compiled from Federal and State agency data sets and enables the user to conduct geographic and analytical studies on mine impacts on the public and environment.

Quality Data Asset includes all current and historical data on the quality of water with regard to the presence of water pollutants of all kinds regulated by the Clean Water Act. Under the new Interagency Agreement with the Department of Energy (DOE), the Radiation & Indoor Environments National Laboratory (R&IE), Office of Radiation and Indoor Air (ORIA), EPA, located in Las Vegas, NV, conducts a Long-Term Hydrological Monitoring Program (LTHMP) providing laboratory sampling/analysis and Quality Assurance and Control to measure radioactivity concentrations in the water sources near the sites of former underground nuclear explosions. The results of the LTHMP provide assurance that radioactive material from the tests have not migrated into water supplies.

Quality Data Asset includes all current and historical emergency radiological response event and incident of national significance data and surveillance, monitoring, and assessment activities, protective action guidelines (PAGS) and environmental sampling and analysis results and other pertinent data to decision makers, modelers, emergency responders, and to the public.

EPA evaluated the total mercury representative of several subsurface locations in OU1 for the purpose of the Human Health Risk Assessment investigation. EPA published this data in support of the Carson River Mercury NPL Site in Nevada. Data was compiled and evaluated for the OU1 Remedial Investigation Report (EPA, 1994), which describes the nature and extent of contamination from the Site. The reports contain the Human Health Risk Assessment and Ecological Risk Assessment Reports. Literature and other source Hg data are summarized in the RI report for upland source areas.
