Field and Laboratory Methods Development and Application

The Toxic Substances Hydrology (Toxics) Program's technology transfer includes making available to practitioners new environmental measurement methods through its web site and publications. USGS scientists develop new methods to measure a wide range of environmental properties, such as the concentration of new contaminants of concern in water or new ways of measuring the properties that control the fate of contaminants in ground water and streams.

Selected recent methods contributions:

• New Information on the Long-Term Fate of Ammonium in Ground Water
• USGS Patents Bioreactors that Treat Nitrate and Methyl Bromide Contamination
• Tracing Wastewater - Using Unique Compounds to Identify Sources of Contamination
• USGS Develops Geophysical Methods to Improve Remediation Monitoring and Site Characterization
• Multidisciplinary Approach to Remediating Watersheds Contaminated from Abandoned Mine Lands
• New Method for Mapping Tritium Contamination
• USGS Patents the Multifunction Bedrock-Aquifer Transportable Testing Tool (BAT³)
• Method to Measure Pharmaceuticals in Water
• Method for Assessing Bed Sediment Contamination
• Field Method for Detecting Chromium VI in Ground Water
• Lab methods to measure new contaminants in aquatic environments
• Using Plants To Detect Tritium Contamination
• Measuring Pesticides and How They Transform in the Environment
• Measuring Metals in Streams: Daily Variations Can Confound Studies
• New Diffusion Samplers Track Contamination Entering Lakes and Ponds
• Handbook on Permeable Reactive Barriers
• Glacial Ice Cores Reveal the History of Global Mercury Contamination
• Improving Cleanup of Contamination from Oil and Gas Production
• USGS Abandoned Mine Lands Initiative

The Toxics Program also transfers new technology to beneficiaries through the following mechanisms:

• Publications
• Training Courses, Workshops, and Lectures
• Conference Sponsorship
• Model Development, Improvement, and Application
