USGS Develops Geophysical Methods to Improve Remediation Monitoring and Site Characterization
U.S. Geological Survey (USGS) scientists continue to develop and adapt new geophysical technologies and data analysis methods for monitoring the performance of remediation systems and for the characterization of contaminated sites. Geophysical monitoring methods are particularly adept at measuring changes in subsurface properties that relate to the presence of water, tracers, contaminants, and...
Multidisciplinary Approach to Remediating Watersheds Contaminated from Abandoned Mine Lands
Since the late 1990s, the U.S. Geological Survey (USGS) has conducted an Abandoned Mine Lands (AML) Initiative . The initiative provides technical assistance to support actions by Federal Land Management Agencies in the U.S. Department of the Interior and the U.S. Department of Agriculture (USDA) to remediate contamination associated with abandoned hard-rock mining sites. Acid drainage and toxic...
Ground-Water Recharge Affects Fate of Petroleum Contaminant Plumes
U.S. Geological Survey (USGS) scientists have discovered that rainwater recharging the water table above petroleum contamination plumes affects how plumes grow and the rate that petroleum products (in this case crude oil) degrade and weather in ground water. The amount of recharge affects the migration of oil in the subsurface, how chemicals dissolve from the oil into ground water, and the...
Glyphosate Herbicide Found in Many Midwestern Streams, Antibiotics Not Common
Researchers with the U.S. Geological Survey (USGS) recently investigated 51 streams in nine Midwestern States to determine the presence of a wide range of herbicides, their degradation byproducts and antibiotics. Herbicides were detected in most water samples, which were collected to coincide with runoff events following herbicide application, but antibiotics were detected in only 1 percent of the...
National Reconnaissance of Pharmaceuticals, Hormones and Other Organic Wastewater Contaminants in U.S. Streams is Making an Impact
The USGS's National Reconnaissance of Pharmaceuticals in U.S. Streams is making an impact in the scientific and regulatory communities.
National Reconnaissance of Pharmaceuticals, Hormones, and Other Organic Wastewater Contaminants in Streams Named as One of the Top 100 Science Stories of the Year
Discover Magazine has named the Toxic Substances Hydrology Program's "National Reconnaissance of Pharmaceuticals, Hormones, and Other Organic Wastewater Contaminants in Streams" as one of the 100 top science stories of 2002.
