Regulations Target Underground Tanks
When Congress passed the Hazardous and Solid Waste Amendments of 1984, (RCRA), underground storage tanks were considered to be a major threat to the country's water supplies....
A Flood in the Desert
Since 1982 the Great Salt Lake has risen from an elevation of 4,200 ft above mean sea level to a historic high of 4,211.85 ft in June 1986. The sharp rise in the lake has caused considerable...
Waves in the Water Works
The 1986 amendments to the 1974 Safe Drinking Water Act are far reaching laws that may affect many drinking water utilities across the nation in the next decade. Congress passed legislation...
A Watery Grave
Subseabed disposal may be the most acceptable means of dealing with radioactive wastes. Land disposal sites are difficult to find and politically difficult to use. Little research has...
Taking Water to Market
If the West is to enjoy continued population growth and economic development, huge volumes of water must be switched from farming to municipal uses. A free market in water will encourage...
Extent of Ground Water Contamination in the U.S.: An Overview
The contamination of ground water may result from all aspects of human activities: agriculture, industry, transportation, domestic wastes and resource exploitation. The contamination due...
Engineering Aspects of Point Versus Nonpoint Sources of Groundwater Pollution
Pollution of groundwater may occur due to a number of sources. These may be categorized into point and nonpoint sources of contamination. The purpose of this paper is to explore the issues...
Survey of Groundwater Contamination in Massachusetts
Public water supplies in Massachusetts have been contaminated or threatened from a number of sources. The purpose of this paper is to outline the nature of groundwater contamination and...
Synthetic Organic Contaminants and Pesticides in Groundwater
For decades, the groundwater of Suffolk County, New York, has been bacteriologically and chemically of superior quality despite the high iron and manganese occasionally encountered in...
Technical Issues of Ground Water Data
Three fundamental issues to be considered in the design of ground water monitoring programs are 1) choice of parameters for characterizing contaminant sources, 2) determining the areal...
A Call for New Directions in Drilling and Sampling Monitoring Wells
The hollow-stem auger drilling technique has an inherent limitation of disturbing large volumes of subsurface materials around the borehole, thereby possibly affecting local permeabilities...
Managing Ground Water Data
Decisions concerning ground water protection and public health should be based on all relevant data, measured and analyzed with technically valid techniques. In areas where ground water...
Techniques for Delineating Subsurface Organic Contamination: A Case Study
Selection of techniques to detect and map subsurface organic contamination depends on the type of source, contamination, and hydrogeologic setting. Ideally, an investigator, manager, or...
Some Problems in the Engineering of Ground Water Cleanup
The problems facing engineers, often civil engineers, in addressing ground water contamination are both exotic and mundane, but all are critical to success. The paper provides a brief...
Control of Groundwater Contamination: Case Studies
Engineered solutions to groundwater contamination problems are being proposed at many hazardous waste sites, yet the effectiveness and long-term reliability of many of these proposed solutions...
Best Management Practices for Point and Nonpoint Sources of Groundwater Contamination
Management strategies have included regulations to guide or limit development in aquifer recharge areas and in the capture zones of public wellfields, engineering requirements to minimize...
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...
Emergency Response
A spill normally has five phases; namely, the initial emergency response, the site assessment, the development of a remedial action plan, the implementation of the remedial action plan,...
When to Remediate: Remediation or Reparations
The 1986 reauthorization of the Comprehensive Environmental Response, Compensation, and Liability Act (Superfund) forcefully stated Congress' desire to see our nations hazardous...
Biological Treatment of Trichloroethylene
Trichloroethylene and related compounds such as cis- and trans-1,2-dichloroethylene and vinyl chloride are common contaminants of ground water in industrial areas. In oxygenated ground...
