Abstract

Understanding groundwater-flow pathways, gradients, and contaminant mass flux distribution is essential for proper remedial design, risk determination, and evaluation of remediation effectiveness. Conventional long-screened wells are not ade- quate for determining groundwater and contaminant flow pathways in three dimensions. Therefore, flux distribution estimates resulting from non-discreet well measurements can be flawed. The objective of this project is to demonstrate the use of the high-resolution piezocone direct push sensor probe to determine direction and rate of groundwater flow in three dimensions. Field measured hydraulic conductivity, head, effective porosity and calculated seepage velocity distributions can be estimated through interpolation methods recently incorporated into Groundwater Modeling System. Probe data comprised of soil type and co-located hydraulic information is particularly amenable to innovative data fusion based interpolations available through the modeling platform. Following chemical concentration data collection, these innovative data processing approaches allow for the determination of flux distributions at resolutions and spatial configurations never before available. Field scale data collection, interpolation, and modeling results from de- ployment at a site in Port Hueneme, California, in 2006 and 2007 will be presented and discussed.
