Concentrated Animal Feeding Operations (CAFOs) and Nitrogen Conversions in the Groundwater Environment
EPA's regulatory focus on concentrated animal feeding operations has historically concentrated on potential surface water impacts from direct discharges as well as nutrient-laden runoff....

Probabilistic Analysis of Long-Term Aquifer Recharge
Long-term time series of aquifer recharge and other aquifer fluxes (aquifer discharge, groundwater extraction) are essential to monitor and understand aquifer processes. This paper presents...

Optimization of Well Placement in Groundwater Long Term Monitoring Networks
Long Term Monitoring (LTM) networks play critical roles in tracking the migration of contaminants in groundwater, evaluating the efficiency of the existing remediation techniques, and...

Analytical Solutions for Coupled Reactive Transport Equations
Modeling the transport of reactive contaminants is one of the key challenges faced by groundwater engineers worldwide. Specifically, problems involving the transport of sequentially decaying...

Modeling Fort Ord Site OU2's Remediation System Using Optimization
Fort Ord.s Site OU2 is located approximately 80 miles south of San Francisco near Monterey Bay in Monterey County, California. Fort Ord contains two landfills which were used for residential...

Characterizing the Pathways and Characteristics of Nutrients Discharging from Ground-Water to Surface Water
Any investigation of surface-water quality for a lake or pond requires accurate estimates of the contributing contaminant or nutrient loads. In many cases, inflow from the adjacent ground...

Characterization of Interaction of Surface Water and Groundwater in the El Paso Lower Valley of Texas
El Paso is located in the Chihuahua desert and prone to long periods of extreme drought. With the river drought, regional irrigation districts only received 34% and 38%of a full water...

Predicting Losses of Phosphorus in the Humid Tropics Using a Modified Version of GLEAMS

Hydrochemical Modeling of Water Quality in a Ground and Surface Water System within a Semi-Urban Watershed

It's a Bug's Life — Enhanced In-Situ Bioremediation of Chlorinated Solvents in Groundwater

Liquid Assets
Educational Facilities and the fountains of a new plaza are making good use of water from a system that is remediating contaminated groundwater in Wichita, Kansas....

Long-Term Groundwater Monitoring

Prepared by the Task Committee on the State of the Art in Long-Term Groundwater Monitoring Design of the Environmental and Water Resources Institute of ASCE. ...

Integrated Water Management for the 21st Century: Problems and Solutions
Most of the projected global population increases will take place in third world countries that already suffer from water, food, and health problems. Increasingly, the various water uses...

Impact of Ground Water Management on the Hydropattern of Wetlands
In this paper, we examine the effect of altering the pumping rates of a large municipal well field, on the hydropattern of the near by PENSUCO wetland. A flow model developed earlier using...

Practical Groundwater and Conjunctive Water Optimization
The Simulation/Optimization MOdeling System (SOMOS) makes it easy to do groundwater optimization modeling for a variety of scales and situations. The SOMOA module uses analytical equations,...

Fate of TCE in Phytoremediation Systems
The phytoremediation of trichloroethylene (TCE) and other volatile organic compounds (VOCs) has been developed from a mere concept to full applications over the past decade. However, the...

Bayesian Approach to Support Design of a Groundwater Long Term Monitoring Plan
This paper discusses a retrospective data assimilation approach that allows one to examine the spatial and temporal differences between forecast and observed states. Their stability, or...

Supercharged
The Groundwater Replenishment (GWR) System is a regional water supply project sponsored jointly by the Orange County Water District (OCWD) and the Orange County Sanitation District (OCSD)....

Impact of Scaling Rule on Simulating the Transport of DNAPLs
Due to the pollutants from lots of industry sewage and organic solvents, they arelow solubility in water and hard to decompose in nature, didn.t treated adequately, itwill cause the ground...

Coming to the Surface
In the past few years, the coastal areas of the Gulf of Mexico and much of Texas have experienced less than normal rainfall and record water demands. During this period, average daily...
