Bedrock and soil geochemistry from Voyageurs National Park, Minnesota Bedrock and soil geochemistry from Voyageurs National Park, Minnesota
Bedrock, forest floor, and mineral soil sampling in Voyageurs National Park (VNP), Minnesota in 2000 and 2001 is part of a multidisciplinary project that includes the U. S. Geological Survey, National Park Service, University of Wisconsin – La Crosse, Minnesota Pollution Control Agency, and the Minnesota Department of Natural Resources. The joint project is examining the distribution of...

A two-dimensional hydrodynamic model of the St. Clair-Detroit River waterway in the Great Lakes basin A two-dimensional hydrodynamic model of the St. Clair-Detroit River waterway in the Great Lakes basin
The St. Clair-Detroit River waterway connects Lake Huron with Lake Erie in the Great Lakes basin to form part of the international boundary between the United States and Canada. A two-dimensional hydrodynamic model is developed to compute flow velocities and water levels as part of a source water assessment of public water intakes. The model, which uses the generalized finite-element...

Determination of methyl mercury by aqueous phase ethylation, followed by gas chromatographic separation with cold vapor atomic fluorescence detection Determination of methyl mercury by aqueous phase ethylation, followed by gas chromatographic separation with cold vapor atomic fluorescence detection
A recent national sampling of streams in the United States revealed low methyl mercury concentrations in surface waters. The resulting median and mean concentrations, calculated from 104 samples, were 0.06 nanograms per liter (ng/L) and 0.15 ng/L, respectively. This level of methyl mercury in surface water in the United States has created a need for analytical techniques capable of...

Surface-water quality-assurance plan for the Wisconsin district of the U. S. Geological Survey, Water Resources Division Surface-water quality-assurance plan for the Wisconsin district of the U. S. Geological Survey, Water Resources Division
This surface-water quality-assurance plan documents the standards, policies, and procedures used by the Wisconsin District of the U.S. Geological Survey, Water Resources Division, for activities related to the collection, processing, storage, analysis, management, and publication of surface-water data. The roles and responsibilities of District personnel in following these policies and...

Water-quality parameters and benthic algal communities at selected streams in Minnesota, August 2000 - Study design, methods and data Water-quality parameters and benthic algal communities at selected streams in Minnesota, August 2000 - Study design, methods and data
Water-quality measurements and benthic algal samples were measured or collected from select Minnesota streams as part of a multiagency (Minnesota Pollution Control Agency, Minnesota Department of Natural Resources, U.S. Environmental Protection Agency, and U.S. Geological Survey) study. The goal of the multiagency study was to identify quantifiable thresholds of water-quality impairment...

Flow distribution in selected branches of St. Clair and Detroit rivers Flow distribution in selected branches of St. Clair and Detroit rivers
St. Clair and Detroit rivers, which are connecting channels between Lake Huron and Lake Erie in the Great Lakes basin, form part of the boundary between the state of Michigan and the province of Ontario. In 13 reaches, this flow divides locally around islands and dikes to form 31 branches. This study develops a set of simple linear regression equations for computing expected flow...

Water-Resources Investigations in Wisconsin, 2002 Water-Resources Investigations in Wisconsin, 2002
The statewide average precipitation of 34.83 inches for the 2001 water year was 3.15 inches greater than the normal annual precipitation of 31.68 inches for water years 1961–90. Average precipitation values affecting streamflow conditions ranged from 92 percent in northeast Wisconsin to 122 percent in southwest Wisconsin with a statewide average of 110 percent (summary tables provided by...
