Long-Term Effects of Urban Stormwater on Wetlands
In 1986 scientists and managers associated with local, state, and federal agencies that have wetland protection and stormwater management responsibilities in the region joined to consider...
Artificial Recharge of Ground Water
A need for international and interdisciplinary technology transfer on the subject of artificial recharge resulted in the American Society of Civil Engineers' (ASCE) Irrigation...
Monitoring for Hazardous Waste Leaks
It is safer and cheaper to keep hazardous wastes out of the groundwater and the ground than to remove them. But better monitoring will be required. In this three-part article, the first...
Burying the Nuclear Past
The Uranium Mill Tailings Remedial Action Program involves reclaiming 24 tailings piles. The work is done in terms of Federal Legislation to prtect the environment and people from the...
Courting Public Opinion

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 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...
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...
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...
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...
