Fate and transport models are used by risk assessors to estimate the movement and chemical alteration of contaminants as they move through environmental media (e.g., air, soil, water, groundwater).
Understanding the processes controlling subsurface
transport is a key element in the demonstration of safe disposal of radioactive and/or hazardous wastes, as well as the design and implementation...
Years of mining for heavy metals has resulted in abandoned mines that are a source of ground- and surface-water contamination in many areas of the United States. To gain an understanding of the...
Mercury has been well known as an environmental pollutant for several decades. As early as the 1950's it was established that emissions of mercury to the environment could have serious effects on...
This open course curriculum focuses on the geotechnical aspects of hazardous waste management, with specific emphasis on the design of land-based waste containment structures and hazardous waste...
The ammonium (NH4+) dissolved in ground water in the center of a contaminant plume on Cape Cod, Massachusetts, has persisted for decades after it entered the subsurface, while other forms of nitrogen...
Abstract of the U.S. Geological Survey report with a link to a PDF version of the full report. Abstract includes Table of Contents and lists of figures and tables.
In 2002, the National Water-Quality Assessment (NAWQA) Program of the U.S. Geological Survey (USGS) implemented Source Water-Quality Assessments (SWQAs) to characterize the quality of selected rivers...
A key objective of the Toxic Substances Hydrology (Toxics) Program is to understand the physical, chemical, and biological processes that control contaminant transport in surface water.
