Data from Most Monitoring Wells in Limestone Terranes Are Irrelevant to Pollutant Detection but Reliable Monitoring Can Be Attained: Why and How
The conventional system of using three or more monitoring wells placed down-gradient from a site and one or more background wells placed up-gradient from it is extremely unlikely to detect...

Effects of Sampling Equipmenton the Chemical Integrity of Groundwater Samples
Proper sampling of groundwater is one of the basic steps in monitoring movement of pollutants in groundwater systems. The effect of the use of silicone rubber when used as a bladder in...

Treatment Facilities and Costs for the Removal of Radon from Ground Water Supplies
Two methods for removal of Radon from drinking water are considered: activated carbon adsorption and packed tower aeration. Although both granular activated carbon (GAC) and packed tower...

Removal of EDB from Groundwater by Granular Activated Carbon Filtration
Application of ethylene dibromide (EDB) pesticide to crops may result in contamination of groundwater. Various water treatment alternatives are: granulated activated carbon adsorption,...

Subsidence by Rising and Fluctuating Ground Water
Present studies by the U. S. Bureau of Reclamation in California indicate that under certain geologic conditions similar subsidence can also be caused by rising ground-water levels, which...

Expert Pattern Recognition for Pollution Source Identification
This paper presents an approach for developing an Expert System to aid the identification of locations and magnitudes of a finite number of groundwater pollution sources. A pattern recognition...

Artificial Recharge for Managing the Great Salt Lake
During the past three years, precipitation amounts throughout the drainage basin have significantly exceeded normal values. The resulting record breaking inflow volumes and lower than...

Conjunctive Use and Managed Groundwater Recharge: Engineering and Politics in Arid Lands
In regions with alluvial groundwater basins, increasing consumer demands for water, irregular surface water flows, and high evapotranspiration rates, managed recharge and long-term conjunctive...

Modeling an Alluvial Aquifer with Flood Irrigation
Interaction between an unconfined alluvial aquifer, recharged by flood irrigation, and the associated stream system in a glacial outwash area of Wyoming was studied. The United States...

Simultaneous Pumping from Layered Ground Water
Laboratory experiments with a Hele-Shaw model and a sand model, and an approximate mathematical analysis using finite elements and the computer, have demonstrated that fresh water can...

Surface Water Analysis for Ground Water Simulation
The California Department of Water Resources (DWR) has applied a hydrologic-economic modeling (HEM) system to the analysis of ground water use in the San Joaquin Valley. An important component...

Investigating and Treating Chromium in Ground Water at a Wood Treater in California
A wood treating facility, operating for more than five years without required permits, contaminated soil and ground water on and offsite. The company moved slowly in response to enforcement...

Remedial Action Alternatives for Groundwater Contamination
Preliminary remedial action alternatives are formulated for a site contaminated by heavy metals. The results of soils and hydrogeologic investigations are summarized and three corrective...

Liquid Waste Pollution from a Sugar Cane Industry
The water pollution survey as performed in this study, indicates that all liquid wastes from the mill are segregated. The chemical waste sewerage systems supposedly conveys these wastes...

Effects of Artificial Recharge on Ground-Water Quality, Long Island, New York
Artificial-recharge experiments were conducted at East Meadow in central Nassau County, Long Island, N. Y. , from October 1982 through January 1984, to evaluate the degree of ground-water...

Design and Construction of TCE/PCE Removal Facilities
This paper presents a review of the design and construction of a facility in Arcadia, California, to remove trichloroethylene (TCE) and tetrachlorethylene (PCE) from groundwater. The City...

Groundwater Quality Monitoring in the New York Metropolitan Area: Statistical Alternatives
The need for development of groundwater monitoring strategies for the New York metropolitan area with emphasis on statistical analysis has been investigated in this study. Statistical...

Uncertainties in Groundwater Transport Modeling
Using synthetic data from a hypothetical aquifer, the effects of data availability and data uncertainty were studied by the combined use of a parameter identification (PI) algorithm and...

Estimation and Inference in the Inverse Problem
The estimation of groundwater flow and mass transport parameters is approached via maximum likelihood. Confidence intervals and hypothesis tests as well as the asymptotic properties of...

Mixed Solute Interactions in Groundwater Systems
Research results are presented from a study examining the competitive sorption effects of two organic chemicals, para-dichlorobenzene and 2,4-dichlorophenol, to solids from the Cohansey...
