Colorado Plateau Environmental Laboratory
We provide support for field surveys and laboratory analysis services.
Total mercury analysis using a Teledyne Leeman Hydra-C. We can analyze semi-solid solid samples, with a detection limit of 1.0 nanograms of total mercury. The analyzes included all trophic levels of aquatic reticulture, aquatic sediment, terrestrial soil, and food supplements.
Sediment coring studies
Recovery and analysis of sediment samples in lakes, reservoirs, and swamps to reconstruct models of environmental changes. At dock scale, stories of atmospheric depositions and sediment delivery can be assessed. At the lake scale, stories of primary productivity and oxygen reduction in the water column can be estimated.
Sedimentation rates in lakes and basins can be assessed using plutonium isotopes (239Pu + 240Pu) to detect the start (1952) and peak (1964) of above-ground atomic tests. Other indicators, such as lead isotopes linked to stories of leaded petrol, major storm events and seizure dates, can be used to match sediment cores seats with calendar dates.
Geophysics aquatic sediments
Sub-fund seismic profiling and sonar side-scan surveys, combined with sediment coring studies, can provide information on the spatial extent of sedimentation in basins.
The isotopic analysis of plutonium and lead
Stable isotopes of lead and plutonium can be prepared in the Environmental Mercury Laboratory and analyzed using the instrumentation available in the Colorado Plateau Environmental Laboratory.
Monitoring of water quality
The Mercury Environmental Laboratory has access to a complete range of field equipment and instrumentation.
