Subsurface Point-Source Contamination
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 -- from the Amargosa Desert Research Site
The Toxics Program conducts intensive field investigations to study common classes of subsurface
point-source contamination. (more information)
