Water Policy and Management: Solving the Problems in Southern New Jersey
Southern New Jersey, which has relied solely on groundwater to satisfy its water supply needs, is depleting the primary source for that water. Symptoms of this depletion include declining...
Joint Optimization of Groundwater Remediation and Monitoring
We describe the challenge of devising optimization methods which optimize jointly the remediation and monitoring at a contaminated site. We refer to the dual control method as a promising...
Decision Support System for Conjunctive Use Under Complex Water Right Conditions
A prototype microcomputer based decision support system (DSS) is presented for assisting in the conjunctive use management of surface and groundwater under the water rights doctrine of...
Aquifer Storage and Recovery at the Centennial Water and Sanitation District
water in a suitable aquifer, the peak time capacity of CWSD could be increased while delaying the water treatment plant (WTP) expansion currently scheduled for 1996. To validate this assumption,...
Evaluation of the Water Supply Potential of the Floridian Aquifer in Seminole County, Florida
In Seminole County, Florida, a occurred in the 1980s and early 1990s due to a large influx of residents. This large increase in demand, when coupled with a limited groundwater supply,...
Computer Simulation Model of the Integrated Local Water Supply Plan for the City of Wichita, Kansas
The City of Wichita, Kansas will require additional water supply sources to meet projected future water demands. A study of options identified a supply plan with integrated use of local...
Brackish Groundwater and Urban Runoff: Source of Supply or Source of Problems?
The Sweetwater Authority hopes to be less dependent on imported supplies in water-short years, and has a goal of developing several alternative sources, including local runoff, brackish...
How Many Observation Wells Does it Take to Find a Groundwater Contamination Plume?
A Bayesian data worth framework is developed to balance the benefits and costs of data collection. In addition to Bayesian decision analysis, tools from Monte Carlo simulation, numerical...
Sewers and Computers
The following is a description of a project performed to reduce excessive infiltration and inflow in a municipal sanitary sewer system and to provide the municipality with a computerized...
Computerized Building Settlement Analyses for a Contaminated Groundwater Remediation Project
The use of spreadsheets is becoming ever more popular in the practice of civil engineering. Engineers are able to use this tool to meet deadlines which were once insurmountable. This paper...
An Object-Oriented Approach to PC Finite-Element Solutions
A methodology for developing a finite-element program with a variety of applications within civil engineering is presented. Application include simple structural analysis, groundwater...
A Real-Time Graphical Interface to a Two-Dimensional Groundwater Flow and Mass Transport Model
This paper describes the implementation of a graphical interface to the U.S. Geological Survey's Method of Characteristics (MOC) groundwater flow and mass transport model....
Sensitized Photooxidation of Dissolved Sulfides in Water
The ability of methylene blue (MB) and riboflavin (RF) to sensitize dissolved sulfides for photooxidation was investigated. Both MB and RF were found to be effective sensitizers for the...
A Coupled Mass Transfer and Surface Complexation Model for Uranium (VI) Removal from Wastewaters
A remediation technique has been developed for removing uranium (VI) from complex contaminated groundwater using flake chitin as a biosorbent in batch and continuous flow configurations....
Pilot Test on Groundwater Organics Removal by Low-Pressure Membranes
A 1-year membrane pilot study has been performed to evaluate disinfection-byproduct (DBP) precursors and color removal by low-pressure membranes from groundwater with color values up to...
Computer simulation of pulsed pumping for remediation under mass transfer limited conditions
The article presents the computer simulation of choosing the right time periods for interruption and pumping in the pulsed pumping process. It will calculate a set of criteria under mass...
Biodegradation of Phenanthrene in Sand Columns in the Presence of Nonionic Surfactants
The effects of three nonionic surfactants on phenanthrene (C14H10) removal and mineralization by aerobic bacteria...
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...
Artificial Recharge of Aquifers
Artificial groundwater recharge is a means of replenishing groundwater supplies with surface water which might otherwise be lost. Artificial groundwater recharge has also been used to...
Thermally Enhanced Bioremediation of a Gasoline-Contaminated Aquifer Using Toluene Oxidizing Bacteria
The combined application of steam injection and vacuum extraction has proved to be very effective for the in situ remediation of a gasoline contaminated aquifer. It is expected that the...
