The Delineation and Management of Wellhead Protection Areas
The delineation and protection of a management zone around specific wells or wellfields will undoubtedly become more common as the 1986 Amendments to the Safe Drinking Water Act are implemented...

Hydrogeologic Investigations at a Superfund Site in Wisconsin
An estimated 10,000 drums of volatile organic wastes from a nearby manufacturing plant were dumped at a landfill site in southern Wisconsin. Chemicals released from these drums have contaminated...

Nuclide Migration from Areal Sources Into a Fracture
The authors show analytic solutions to the problem of hydrogeologic transport of radionuclides released from finite areal sources into a planar fracture. The authors illustrate the solutions...

Groundwater Vulnerability to Contamination: A Literature Review
Methods are needed to allow regulatory agencies and resource managers to predict, from readily available data, the potential for groundwater contamination problems. Regional maps developed...

Groundwater Modeling - A Management Tool
A hydrogeologic investigation within the South Mountain Complex of south central Pennsylvania was performed to develop a groundwater management program. Using LandSat imagery, low altitude...

Hydrogeologic Investigation of the Chillicothe, Ohio Landfill
A hydrogeologic investigation of a municipal waste landfill determined that the local surface and ground water are being polluted. Water quality monitoring and aerial photography were...

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...

Geohydrologic Considerations in Ground Water Modeling
Ground water modeling is an effective engineering and management tool for evaluating complex hydrogeologic situations in a cost effective manner. Objectives of a particular study dictate...

The National Ground Water Information Center Data Base
The Research Institute, Education Foundation and Publishing Company of the National Water Well Association have long been considered information central for the world's community of hydrogeologists....

Ground-Water Flow Model of Soda-Ash Waste Beds
A recent application by a steel manufacturing plant to obtain a permit for an industrial landfill located on top of abandoned soda-ash waste beds in the City of Syracuse, New York, resulted...

The National Water Well Association's Ground Water Software Centre
The National Water Well Association (NWWA) offers a new service to the members of the ground water industry. NWWA's Ground Water Software Centre markets computer programs...

Arsenic Contamination of Private Potable Wells
The results of a series of water testing programs of private residential wells in Pepperell, Massachusetts showed that of 301 wells tested, approximately 12 percent exhibited arsenic levels...

Hydrogeologic Controls on Leachate Migration
The Brown Station Road Landfill is a municipal solid waste disposal site operated by Prince George's County, Maryland. The work described herein was conducted as part of a...

Evaluation of a Contaminated Aquifier's Restoration Potential

Predicting Ground-Water Drainage to Surface Mines
A two-dimensional, finite-difference numerical model is used to simulate the drainage of ground water into a surface coal mine. Graphs of dimensionless head as a function of dimensionless...
