Taschenbuch. Zustand: Neu. Neuware - This research effort analyzed groundwater flow paths within a treatment wetland constructed to degrade tetrachloroethylene (PCE) in groundwater. The treatment cell is a vertical flow wetland that allows the water to flow from the bottom to the surface breaking down PCE and daughter products. The method of conducting this research included collecting field data of hydraulic head contours nested piezometers and collecting data from sampling wells to determine hydraulic conductivities in the wetland. The field data was used to create a numerical computer model to determine groundwater flow patterns. The field data and the model demonstrate that there are areas in the wetland with flow velocities as low as 0.0019 m/day and as high as 2.779 m/day. The computer model also shows residence times of water particles traveling from the bottom of the wetland cell to the surface water varying from lt; 1 day, to over 1000 days.…

Taschenbuch. Zustand: Neu. Neuware - Past research (Oshiba, 1997) has shown that there is a rising public concern with environmental issues in the Republic of Korea (ROK). As Korean government and public interest in the environment grow, there is likely to be increased pressure to remediate environmental contamination at United States Department of Defense (DoD) installations in Korea. Impacting DoD's ability to remediate contaminated sites overseas is the fact that limited environmental funds must compete with high priority mission requirements. Thus, particularly at overseas bases, there is an urgent need for inexpensive and effective groundwater remediation technologies. This study focused on the containment of groundwater contaminated with chlorinated solvents in the fractured rock aquifers that are commonly encountered at DoD installations in the ROK. Horizontal Flow Treatment wells (HFTWs) were analyzed as a potentially cheaper, safer, and more effective technology for the containment of chlorinated solvent contaminated groundwater. Both hydrogeologic and design parameters were varied to determine their effects on the technology performance. From this study, it was determined that an HFTW numerical model developed for porous media is appropriate for application in the fractured systems encountered in the ROK, and that HFTWs have the potential to be a cost effective alternative for contaminant management in fractured media when compared to conventional technologies. Model analysis indicated HFTWs might be appropriate for containing contaminant plumes in the ROK, though bypassing of system may be problematic.This work has been selected by scholars as being culturally important, and is part of the knowledge base of civilization as we know it.
