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.
Characterize the quality of selected rivers and aquifers used as a source of supply to community water systems in the United States to determine the occurrence of about 280 primary unregulated anthropogenic organic compounds.
Suspended-sediment concentration data were collected in San Francisco Bay during water year 2000 using optical backscatterance sensors and water samples. This report presents the data-collection methods, data, and calibration plots.
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.
It is important that we collect samples consistently and properly to assure the quality of the information needed by decision makers. This report explains the procedures for sampling water, sediment, benthic invertebrates, and microorganisms.
Thirty year database of water-quality data, visual data displays, and project information on the San Francisco Bay directed towards following and understanding changes in the water quality of San Francisco Bay.
