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 mercury in

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 code RMA2, di

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 detecting sub-n

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 procedures

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 and establ

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 Lyle Ande

Water use in Wisconsin, 2000
As part of the National Water-Use Information Program, the U.S. Geological Survey (USGS) stores water-use data in standardized format for different catego ries of water use. Information about amounts of water withdrawn, sources of wa ter, how the water was used, and how much water was returned is available to those involved in establishing water-resource policy and to those managing water resource

Estimates of recharge to unconfined aquifers and leakage to confined aquifers in the seven-county metropolitan area of Minneapolis-St. Paul, Minnesota
Recharge to unconfined aquifers in the seven-county Twin Cities metropolitan area of Minnesota was estimated by five methods. Mean recharge estimated as a percentage (27 percent) of precipitation ranged from 7.7 to 8.3 in./yr across the study area. The median recharge estimated from automated analyses of streamflow-recession displacements for seven basins ranged from 1.2 to 12.2 in./yr. Median rec
