Description of Long Island Sound projects and links to research topics, data, publications, photos, and technology on sediment transport, sea floor mapping, contaminant sampling, sediment texture, and environmental issues.
Links to studies at the Amargosa Desert Research Site by the USGS Toxic Substances Hydrology Program studying the subsurface migration and fate of contaminants in arid environments. Links to news, remediation, photos, bibliography and techniques.
Project of the Gulf of Mexico Integrated Science program that evaluates the transport and sedimentation of contaminates through the Mississippi River and Atchafalaya River delta to the near-shore Gulf of Mexico. Includes aerial photographs.
Studies by the USGS documenting the extent of surface-water and ground water degradation associated with coal mining in Pennsylvania and the effects of mining and reclamation practices. Includes map of mine sites.
Overview of fractured rock research aimed at understanding the movement of water through fracture networks, and characterize field conditions influencing contaminant migration. Includes programs and publications.
Site describes studies using flow visualization and rock matrix pressure measurements to study flow through fractures in the unsaturated zone, which plays an important role in water infiltration and contaminant transport.
This site provides information on investigations of hydrocarbons in the unsaturated zone and shallow ground water at a gasoline-spill site in Galloway Township, N.J., with links to research projects, mathematical models, and photos.
