Summary of a circular on USGS environmental research and Chesapeake Bay with links to full document. Includes discussion of the problems of the estuary, restoration efforts, water quality, and effects on ecosystem.
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.
Overview of project assessing water quality of the Tualatin River basin near Portland, Oregon with links to reports on chemical and nutrient levels and selected data on streamflow, water temperature, weather and precipitation.
Water quality is important here because this reservoir is the primary supply for Wichita, Kansas. Due to low streamflow during the monitoring period, we expect suspended sediment and phosphorus to be more variable in the future.
Describes cooperation of the USGS office in Las Vegas, Nevada, with the Department of Energy to address environmental and scientific issues at the Nevada Test Site and vicinity with links to project information.
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.
Description of project to study the distribution of saline water in the aquifers of the Coastal Plain of Virginia and the potential for saline water intrusion by evaluating chloride concentrations and the factors affecting chloride distribution.
