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.
Broad overview of USGS research and monitoring designed to understand current changes in the context of prehistoric and recent earth processes, distinguishing between natural and human-influenced changes, and recognizing ecological and physical responses
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.
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 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.
Describes the studies of five small watersheds, four in the U.S. and one in Puerto Rico, under the WEBB program to understand the processes controlling water, energy, and biogeochemical fluxes with links to other watershed research.
