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.
