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.
Boston Harbor/Massachusetts Bay Studies research project conducted as part of Boston Harbor cleanup to predict the fate of contaminants and sediments introduced to Massachusetts' coastal waters from sources that include Boston sewage outfall.
Pavement sealant contains chemicals that are known carcinogens, which get into nearby homes, lakes, and the air. Sealants based on coal tar release more dangerous chemicals than those based on asphalt.
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.
Describes project to identify sources of fecal coliform bacteria by ribotyping to develop the use of Maximum Daily Load (TMDL) values for contaminated stream segments in Virginia.
Homepage for the research on occurrence, movement, flux, fate, and effects of agricultural chemicals, such as pesticides, in 25 states by the Midcontinent Agricultural Chemical Research Project (MACRP) with links to study results and publications.
Overview of aspects of research on pesticides and herbicides in Midwestern rivers with collection of data, results over a period of time, online publications, and bibliography.
Report on the use of regression equations from measurements made by water quality monitors and analytical results of manually collected samples estimating nutrient, bacteria, and other constituent concentrations to study streams in Kansas.
Links to science programs on upper Midwest river inventory and monitoring with links to databases on macroinvertebrates, fisheries, vegetation, water quality, bathymetry, floodplain forest, wildlife, sediment, contaminants and nutrients.
A software model for regional interpretation of water-quality monitoring data, estimating origin and fate of contaminants in streams, with documentation, publications and data for the applications.
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.
Report (PDF format) on an evaluation of the potential environmental impacts of contaminated ground water from a metals refinery adjacent to the Missouri River in Omaha, Nebraska testing water and sediments for contaminants and toxicity.
Research on contamination by trichloroethylene (TCE) in fractured rock at the Naval Air Warfare Center in Trenton, N.J. with links to site description, bibliography, online reports, and findings.
Describes and provides links to USGS research in the location of the estuary and coast of Long Island, New York, to map the sea floor and to study sediment transport, contaminants, and sand resources and coastal vulnerability.
Outlines processes that control the release of metals and acidic waters from inactive mines and mineralized areas, the transport of metals and acidic waters to streams, and the fate and effect of metals and acidity on downstream ecosystems.
Program to measure streamflow stage and discharge at four sites in the Upper Wallkill River Valley's Black Dirt Region and determine Total Suspended Solids (TSS) concentration data and estimate loads of TSS and sources of contaminants.
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.
Description of a project to develop watershed models that can be used to track sources of fecal coliform bacteria by assigning Total Maximum Daily Loads (TMDL) to three stream segments in Virginia.
Description of river input monitoring project's collecting and analyzing water-quality data to calculate and explain load and trend estimates of selected nutrients and suspended solids for five major river basins in the Chesapeake Bay watershed.
Explains how mathematical simulations of watershed properties can help us understand the likely behavior of the water systems, putting the choices available to people in better perspective.
