An Evaluation And Implementation Guide For Current Groundwater Mass Flux Measurement Practices, Jack G. Wheeldon Iii
An Evaluation And Implementation Guide For Current Groundwater Mass Flux Measurement Practices, Jack G. Wheeldon Iii
Theses and Dissertations
Contaminant mass flux is an important parameter needed for decision making at sites with contaminated groundwater. New and potentially better methods for measuring mass flux are emerging. This study looks at the conventional transect method (TM), and the newer passive flux meter (PFM), modified integral pump test (MIPT), and tandem circulating well (TCW) methods. In order to facilitate transfer and application of these innovative technologies, it is essential that potential technology users have access to credible information that addresses technology capabilities, limitations, and costs. This study provides such information on each of the methods by reviewing implementation practices and comparing …
An Analysis Of Groundwater Flow Patterns In A Constructed Treatment Wetland Cell, Rebecca S. Corbin
An Analysis Of Groundwater Flow Patterns In A Constructed Treatment Wetland Cell, Rebecca S. Corbin
Theses and Dissertations
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 …
