Ground Water in the Pacific Rim Countries
This proceedings, Ground Water in the Pacific Rim Countries, consists of papers presented at the Symposium held in Honolulu, Hawaii, July 23-25,...

Ground-Water Modeling Without Fear
Computerized ground-water modeling has leapt from the cloistered laboratory to the field project as more and more programs are written for the personal computer. These easy-to-understand...

Loma Prieta Earthquake?Emergency Response and Restoration: Water and Sewerage Lifelines
Water and Sewerage systems performed very well with a few exceptions in the Loma Prieta earthquake. Pipeline damage occurred in unstable ground. Damage at treatment plants was due to sloshing...

Pumping Oil, Treating Soil
Oil was discovered on hilltop land in Signal Hill, Calif., in 1921, setting off one of the most wild land rushes the state has ever seen. Some 70 years and 20,000 oil wells later, the...

Natural Radionuclides in Groundwater From J-13 Well at the Nevada Test Site
The concentrations of U-238 and Th-232 chain members are extremely low in J-13 water, suggesting that their concentrations in groundwaters are largely governed by sorption/desorption processes....

Simulation of Heat Transfer in the Unsaturated Zone
It is well known that heat transfer can play an important roll in fluid flow near the emplacement site of high-level nuclear waste (K. Pruess and J.S.W. Wang, 1987). Heat transfer effects...

Optimization of a Groundwater Well Monitoring Network
An optimization model is presented for the design of a well monitoring network for groundwater quality and quantity parameters. The model utilizes a geostatistical procedure to estimate...

Groundwater Quality Network Design
This paper presents a methodology that uses optimization for designing a groundwater monitoring network. The methodology incorporates parameter estimation in conjunction with a numerical...

Development of an Optimization Model for Groundwater Withdrawal
An optimization model has been developed to simulate optimal values of withdrawal from a given aquifer system. The linear programming technique has been used to formulate the objective...

Evaluating Spring Flow Trends at Pipe Spring National Monument and Vicinity, Arizona
A study conducted by the National Park Service Water Resources Division is resolving if ground water pumping is causing spring flow declines at Pipe Spring National Monument (PISP). Ground...

Neutron Meters in Statewide Irrigation Programs
These programs have ranged from University demonstrations of new technologies on through completely locally funded and operated programs. The most significant interest has been from those...

Location, Design, and Construction of Water Wells
Proper location, design, and construction of water wells are important to assure their efficient operation and minimize maintenance problems. Detailed and accurate records of the design...

Efficiency Testing of Water Wells
In the operation of a water well, the difference between the water level in the well before pumping starts and after it has been pumping for a period of time is termed 'drawdown.'...

Rehabilitation of Water Wells
The main causes of declining well yield are biological growths, mechanical clogging and chemical encrustation. Because the treatment of the causes of encrustation and clogging is expensive...

Contributions by the Hydraulics Division of ASCE to the Advancement of Ground-Water Hydrology
Papers related to ground-water hydrology published in Proceedings of the ASCE and in Hydraulics Division journals from 1938 through mid-1988 are briefly summarized. The areas covered are...

Pre-Treatment Process Control of a Variable Quality Raw Water Supply
The West Coast Regional Water Supply Authority is the public agency charged with the development of public water supply for the Tampa Bay Area in the state of Florida. The Authority's...

Removal of Priority Pollutants in Wastewater by Secondary Treatment and Groundwater Recharge
Monitoring influent and effluent wastewater for organic priority pollutants at two Tucson-area treatment facilities has shown significant removal rates for commonly detected pollutants....

Transport of Injected Produced Water: A Sensitivity Study
This paper deals with the development and application of a model to assess potential environmental effects on Underground Sources of Drinking Water (USDW) due to the presence of an improperly...

Irrigation and Aquifer Management in Illinois
The ground-water resources in eastern Kankakee and northern Iroquois Counties, Illinois, have been used for irrigation for over 50 years. During the drought of 1988, 131 irrigation wells...

Modeling a Multiple Well Groundwater Supply System
The paper is concerned with the simulation of existing groundwater supply systems. This encompasses the delivery of the groundwater from the wells to the water treatment plant, including...
