Modeling the Lake Decatur Watershed in Illinois to Evaluate Effects of Best Management Practices on Nitrate Loading
The Illinois State Water Survey recently completed a two-year monitoring and modeling study of the Lake Decatur watershed in Illinois to develop land use management alternatives that would...
Artificial Recharge in the Oakes Test Area
The Oakes Test Area (OTA) was developed to evaluate predicted impacts of developing irrigation in the Garrison Diversion Unit in North Dakota. A limited irrigation water supply has forced...
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...

Biotransformation of Pesticides in Simulated Groundwater Columns
Experiments were performed to investigate the biotransformation of the pesticides alachlor, propachlor, atrazine, and bromacil under aerobic and nitrate-reducing conditions. Glass bead...
Denitrification Inhibition by High Nitrate Wastes
The adaptation of activated sludge and inhibition of denitrification at high nitrate concentrations was studied using pH controlled bench-scale sequencing batch reactors (SBRs), operated...
Biological Upflow Fluidized Bed Denitrification Reactor Demonstration Project-Stamford, Ct.
Results of a demonstration project using a biological upflow fluidized bed reactor to remove nitrogen from wastewater treatment plant effluent are described. The reactor was operated at...
Biodegradation of 2,4-Dinitrotoluene in a Two Stage System
An anaerobic/anoxic fluidized-bed GAC bioreactor in series with an activated sludge reactor was used to treat 2,4-Dinitrotoluene (2,4-DNT). A simulated high strength wastewater solution...
DOE Lab Develops System to Sack Sodium Nitrate
Experimental Synthesis of Crystalline Matrices Based on Ce, Ba, Sr Zirconates for Immobilization of High-Level Radioactive Actinides
Experimental investigations are carried out at the Radium Institute to create different by their properties crystalline matrices, alternative to SYNROC, for incorporation of partitioned...
The Use of Geographic Information Systems and Models on Personal Computer and Workstation Platforms, in the Development of a Wellhead Protection Program, Salinas Valley, California
The Salinas Valley is located on California's Central Coast. The ground water basin supports 850,000,000 M2 of irrigated crops which have a market...
