Comparison of Mass Size Distribution and Flux of Sulfate and Nitrate in Urban and Non-Urban Areas
Effect of Ground-Water/Surface-Water Interactions on Nitrate Concentrations in Discharge from the South Platte River Alluvial Aquifer, Colorado
Geohydrology and Water Quality of the North Platte River Alluvial Aquifer, Garden County, Western Nebraska
Applications of Isotopes to Tracing Sources of Solutes and Water in Shallow Systems
Ground Water Bioremediation
Agricultural Chemical Contamination of Shallow, Large Diameter Wells in Illinois
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...
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
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...
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...
Electro-Osmotic Removal of Nitrates from Soils
Nitrate migration to ground and surface waters is a serious U.S. contamination threat. Electro-osmosis may be a more effective means for soil reclamation than leaching or chemical treatment....
Nitrate Contamination of an Alluvial Aquifer Resulting from Irrigation and Geologic Control
A nitrate sampling program was conducted in the vicinity of a rural municipality to determine the source of nitrate contamination of the municipal groundwater supply. A finite-difference...
Farmers' Incentives to Reduce Groundwater Nitrates
Nitrate leaching from irrigated crops is a productive input loss to the farmer and a possible source of environmental degradation. This study uses a simulation model to analyze incentives...
Simulation of Two Approaches to Curb Potential Buildup of Nitrates in Groundwater
Evaluation of
This paper examines the potential application of in-situ bio-dentrification as well as pertinent physical and biochemical factors that control the process to reduce nitrate in groundwater...
Products of Chloramination in Dilute Aqueous Solution
Chloride and nitrate formation was determined in the reaction of chlorine with ammonia in molar excess, in dilute aqueous solution. Nitrate was formed under all conditions investigated....
