Low-Level Radioactive and Mixed- Hazardous Wastes
Collection of soil-water vapor samples for tritium determination. The collection is part is part of a long-term monitoring program on the transport of tritium in the unsaturated zone.
On-site facility for collection of soil-water vapor and unsaturated-zone gas from a deep borehole for tritium and volatile-organic compound analyses. USGS scientists are conducting research on the transport and fate of tritium and other contaminants in desert environments with thick unsaturated zones.
Collection of soil-gas samples for volatile-organic compound analysis. USGS scientists are studying the transport and fate of volatile-organic compounds in the unsaturated zone.
Soil sampling for naturally occurring perchlorate in Amargosa Desert soils.
Inspecting a pit wall for evidence of a geologic fault. Faults can form pathways or barriers to the transport of contaminants in the unsaturated zone.
Belowground and aboveground features and processes being evaluated at the Amargosa Desert Research Site--soil properties, root distribution, transpiration, and evaporation. USGS scientists are quantifying the movement of soil moisture and tritium from the shallow unsaturated zone to the atmosphere.
Eddy covariance station used to measure continuous evapotranspiration from desert soil and plants. The station non-invasively collects atmospheric data that are analyzed to calculate continuous water-vapor flux values.
Hemispherical chamber used to periodically measure evaporation from bare soil. This is one component of research being conducted on how moisture and tritium are transported from the unsaturated zone to the atmosphere.
