Mexican Border Ground Water Agreement
This paper provides a discussion about the challenges in developing a Mexican Botder Ground Water Agreement for the management of shallow ground waters that connect to the surface water...
Cropping Systems on the Delmarva Peninsula to Reduce Ground Water Contamination
A total of twelve cropping systems were simulated with the GLEAMS model for nitrate leaching. A precipitation model was developed using a Markov chain model and a gamma distribution for...
Probabilistic Approach for Cancer Risk Assessment
Carcinogenic chemicals have entered ground water systems from surface spills and leaching from subsurface disposal sites. Of particular interest in this study was the contaminant tetrachioroethylene...
Small Inocula Can Effect
This is the first report of colonization of soil by small numbers of a genetically engineered microorganism. The study suggests that the addition of small inocula of D5 to contaminated...
Computer Optimization of a Groundwater Treatment Facility
A computer model has been developed to optimize the operation of a groundwater oil recovery treatment plant. The site consists of 24 pump and treat recovery wells which lead to a treatment...
Biodegradation Modeling of a Closed Landfill Site
The two-dimensional model, BIOPLUME II, was applied to the closed Becker County Landfill at Detroit township, Minnesota, to study the transport of hydrocarbons occurring at the site. The...
CHEMFLO Modeling of Aquifer Bioremediation in Vadose Zone
This paper deals with bioremediation in the vadose zone with an emphasis on using numerical models as a tool to ensure that the concentration of nutrients is maintained at a required level....
Overview of DoD Research in Groundwater Modeling
The U.S. Army Engineer Waterways Experiment Station leads a multi-agency research program for the Department of Defense (DoD) which continues the development of integrated, comprehensive...
Research to Application: Network Models to Simulate Flow and Transport in Heterogeneous Media
Effective groundwater cleanup requires accurate site-specific information on cleanup processes. Numerical simulations limit the need for expensive field experiments and provide details...
Computational Tools for Subsurface Conceptualization
Development of subsurface conceptual models for use in groundwater flow and transport modeling requires that existing data in the form of boring logs, cone penetrometer (CPT) logs, geophysical...
