U.S. Geological Survey Toxic Substances
Hydrology Program--Proceedings of the Technical Meeting, Colorado Springs,
Colorado, September 20-24, 1993, Water-Resources Investigations Report 94-4015
The Toxic Substances Hydrology (Toxics) Program of the U.S. Geological
Survey (USGS) provides earth-science information needed to prevent or mitigate
contamination of the Nation's ground-water and surface-water resources.
The Toxics Program's objective is to understand the movement and fate of
toxic substances in the Nation's ground water and surface water. The program's
research activities include (1) field and laboratory investigation of the
physical, chemical, and biological processes that control the transport
and fate of contaminants in ground water and surface water; (2) the development
of new analytical methods and sampling techniques to measure the concentrations
of toxic substances in water; and (3) the investigation of the relations
among human activities, environmental characteristics, and regional patterns
of water quality. Most of the research activities take place at contaminated
sites. The major research objective is not characterization of contaminated
sites, but is obtaining knowledge about contaminant-transport processes
transferable to other contaminated sites. For example, the knowledge obtained
at the research sites could be used to predict contaminant transport at
other sites, improve methods for remediating contaminated ground water,
design water-quality assessments, and identify potential causes of contamination.
Recent accomplishments of the Toxics Program have been presented at a
series of technical meetings held in Tucson, Arizona (1984), Cape Cod, Massachusetts
(1985), Denver, Colorado (1987), Pensacola, Florida (1987), Phoenix, Arizona
(1988), and Monterey, California (1991). This report documents the oral
and poster presentations given at the most recent meeting, held in Colorado
Springs, Colorado, in September 1993. The sections in this report correspond
to the topical organization of the meeting's oral sessions. Each session
focused on research at a specific contaminated site or on a topical subject.
Papers associated with poster sessions were integrated into the appropriate
section. The lead paper in most of the sections gives an overview of the
research conducted at the site discussed.
