Water is one of seven science mission areas of the U.S. Geological Survey (USGS). Water's mission is to collect and disseminate reliable, impartial, and timely information that is needed to understand the Nation's water resources.Read Science Plan
Michigan Water Science Center used acoustic meters for about 90 percent of the streamflow measurements made in Fiscal Year 2012. Wading measurements are done using a modified top setting wading rod equipped with an acoustic Doppler velocimeter (ADV). Acoustic Doppler current profilers (ADCP) are used when measurement depths are too deep to wade. ADCP measurements can either be made with a...
Important questions about beach closures and management remain unanswered in the Great Lakes where over 500 beaches are routinely used along the nearly 11,000 miles of coastline. The economies of coastal areas are dependent on public confidence in the quality of water at the shoreline, and beach managers need reliable science-based information to make beach closure and beach management...
Enbridge Energy Partners LLP (Enbridge) reported a 30-inch pipeline ruptured on Monday, July 26, 2010, near Marshall, Michigan. The release, estimated at 819,000 gallons, entered Talmadge Creek and flowed into the Kalamazoo River, a Lake Michigan tributary. Heavy rains caused the river to overtop existing dams and carried oil 30 miles downstream on the Kalamazoo River. As the federal agency in...
The National Water-Quality Assessment Program (NAWQA) provides an understanding of water-quality conditions; whether conditions are getting better or worse over time; and how natural features and human activities affect those conditions. Regional and national assessments are possible because of a consistent study design and uniform methods of data collection and analysis. Monitoring data are...
The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts research on antibiotic-resistant bacteria and their genes. We have concentrated our studies on antibiotic-resistant bacteria of human-health concern, including vancomycin-resistant enterococci, methicillin-resistant Staphylococcus aureus (...
Recreational water and industrial discharges are regulated by other federal and state agencies across the country.

A variety of standardized protocols are used to...
The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts ecological studies on the structure and function of eubacterial and archeal communities in the environment. Studies of this type give us basic information about the composition and functionality of different microbial communities and allow us to investigate the effects that natural and...
It is often important to understand the source of fecal indicator bacteria, pathogens, or chemicals that impair the normal use of water. Antibiotic-resistant bacteria and their genes, specific bacterial pathogens (such as E. coli O157:H7 which is primarily associated with cattle), and host-associated bacterial genes (such as human or animal specific Bacteroides genes), can be used to evaluate...
Recently, elevated chlorophyll-a concentrations were found related to persistent algal blooms on Silver Lake in Oceana County, MI. Elevated chlorophyll-a concentrations, high phosphorus concentrations during summer months, as well as a decrease in water clarity indicated potential accelerated eutrophication processes during the last two years, and underscore a need to characterize water...
The Great Lakes Restoration Initiative (GLRI) was established to accelerate ecosystem restoration in the Great Lakes by confronting the most serious threats to the region, such as nonpoint source pollution, toxic sediments, and invasive species. Three Priority Watersheds have been targeted by the Regional Working Group's Phosphorus Reduction Work Group (Fox/Green Bay, Saginaw, and Maumee)...
In support of the Michigan Department of Environmental Quality (MDEQ) Water Chemistry Monitoring Project, the USGS Michigan Water Science Center has been collecting long-term water quality data for Michigan's rivers and streams. Water samples are collected 4 to 12 times a year for selected nutrients, trace metals, sediment, and other water-quality constituents. Intensive sampling (12...

The genetic basis of anoxygenic photosynthetic arsenite oxidation
“Photoarsenotrophy”, the use of arsenite as an electron donor for anoxygenic photosynthesis, is thought to be an ancient form of phototrophy along with the photosynthetic oxidation of Fe(II), H2S, H2, and NO2-. Photoarsenotrophy was recently identified from Paoha Island's (Mono Lake, CA) arsenic-rich hot springs. The genomes of several...Hernandez-Maldonado, Jamie; Sanchez-Sedillo, Benjamin; Stoneburner, Brendon; Boren, Alison; Miller, Laurence G.; McCann, Shelley; Rosen, Michael R.; Oremland, Ronald S.; Saltikov, Chad W.
Salinity influences on aboveground and belowground net primary productivity in tidal wetlands
Tidal freshwater wetlands are one of the most vulnerable ecosystems to climate change and rising sea levels. However salinification within these systems is poorly understood, therefore, productivity (litterfall, woody biomass, and fine roots) were investigated on three forested tidal wetlands [(1) freshwater, (2) moderately saline, and (3) heavily...Pierfelice, Kathryn N.; Graeme Lockaby, B.; Krauss, Ken W.; Conner, William H.; Noe, Gregory; Ricker, Matthew C.
Groundwater quality in the Coastal Lowlands aquifer system, south-central United States

Implementation and evaluation of a monthly water balance model over the US on an 800 m grid
We simulate the 1950–2010 water balance for the conterminous U.S. (CONUS) with a monthly water balance model (MWBM) using the 800 m Parameter-elevation Regression on Independent Slopes Model (PRISM) data set as model input. We employed observed snow and streamflow data sets to guide modification of the snow and potential evapotranspiration...Hostetler, Steven W.; Alder, Jay R.
Final Laurentide ice-sheet deglaciation and Holocene climate-sea level change
Despite elevated summer insolation forcing during the early Holocene, global ice sheets retained nearly half of their volume from the Last Glacial Maximum, as indicated by deglacial records of global mean sea level (GMSL). Partitioning the GMSL rise among potential sources requires accurate dating of ice-sheet extent to estimate ice-sheet volume...Ullman, David J.; Carlson, Anders E.; Hostetler, Steven W.; Clark, Peter U.; Cuzzone, Joshua; Milne, Glenn A.; Winsor, Kelsey; Caffee, Marc A.
Data on annual total nitrogen loads and watershed characteristics used to develop a method to estimate the total nitrogen loads in small streams
This USGS Data Release represents the data used to develop multiple linear regression models for estimating the loads of total nitrogen in small streams. Recursive partitioning and random forest regression were used to assess 85 geospatial, environmental, and watershed variables across 636 small (less than 585 square kilometers) watersheds to...Kronholm, Scott C.; Capel, Paul D.; Terziotti, Silvia
Permeability is the primary control on fluid flow in the Earth’s crust and is key to a surprisingly wide range of geological processes, because it controls the advection of heat and solutes and the generation of anomalous pore pressures. The practical importance of permeability – and the potential for large, dynamic changes in permeability – is...
