Abstract:: Understanding the processes involved in the transport of dissolved gas plumes in groundwater aquifers is essential for comprehending the effect that these transport processes can have on site characterization and remedial design applications. Previous laboratory and field studies have indicated that dissolved gas transport in groundwater can be greatly affected...

Creator:: Louie, Michael J.
Abstract:: Efficient use of water in agricultural production involves accurate assessment and control of the quantity and spatial uniformity of excess percolation. Passive Capillary Samplers (PCAPS), which sample water from the vadose zone have shown potential to provide superior estimates of soil water flux compared to alternative methods. In a four-year...

Creator:: Zhang, Wenqian
Abstract:: Contamination of ground water by non-aqueous phase liquids (NAPLs) has received increasing attention. The most common approach to numerical modeling of NAPL movement through the unsaturated zone is the use of the finite difference or finite element methods to solve a set of partial differential equations derived from Darcy's law...

Creator:: Humphrey, Mark D.
Abstract:: Groundwater resources have become seriously threatened due to improper use by industrial, municipal, and even public sectors. Widespread contamination of aquifer systems has jeopardized human health and the environment and methods for restoring these systems are needed. Biological and chemical in situ remediation, where contaminants are degraded within the natural...
