| Abstract: Laboratory studies and a field demonstration were conducted to determine the ability of the Snap Sampler to recover representative concentrations of inorganic analytes, including metals, from ground water. For the laboratory studies, concentrations of analytes in Snap Sampler samples were compared with concentrations of the analytes in samples collected from a standpipe (i.e., control samples). These studies clearly demonstrated that Snap Sampler concentrations were comparable to control sample concentrations. ... |

| The manufacturing and testing of energetic compounds TNT, RDX and HMX for military purposes has led to widespread contamination of soils and groundwater in the United States and across Europe. The compounds have been shown to be toxic and are considered pollutants. Phytoremediation has been shown to provide a cost-effective alternative to classical technologies for cleaning up nitro-substituted explosive-contaminated sites, which generally requires excavation followed by incineration or land filling. ... |

|
| A regional MODFLOW ground-water flow model of parts of coastal Georgia, Florida, and South Carolina was used to evaluate the effects of current and hypothetical groundwater withdrawal, and the relative effects of pumping in specific areas on ground-water flow in the Upper Floridan aquifer near Fort Stewart and Hunter Army Airfield (HAAF), coastal Georgia. Simulation results for four steady-state pumping scenarios were compared to each other and to a Base ... |
