Michigan Bacteriological Research Laboratory (MI-BaRL)

The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) is a newly renovated laboratory space operated by the USGS Michigan Water Science Center in Lansing, MI. The laboratory is staffed by two Ph.D. level microbiologists and five M.S. level microbiologists with a combined 70 years of experience in microbiology and water resources research. The USGS MI-BaRL...

Determine Baseline and Sources of Contaminant Loadings to the Great Lakes

To better understand the quality of water flowing into the Great Lakes, the USGS is conducting water-quality analyses for nutrients, sediment, and toxic substances and estimating the amount (load) of these substances for tributaries to the Great Lakes. Information on the occurrence and distribution of contaminants is needed to provide baseline information, measure progress towards restoration...

Acoustics

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...

Groundwater Data Available Online

The USGS Michigan Water Science Center cooperates with local and state agencies to collect and maintain groundwater data across Michigan. The USGS and local partners actively monitor 90 wells. Of these 90 wells, 22 are continuously monitored with 3 of those continuously...

Enhance Great Lakes Beach Recreational Water Quality Decision Making

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...

Response to an oilspill on the Kalamazoo River

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...

NAWQA Groundwater

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...

Antibiotic Resistance

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 (...

Microbiological Water Quality

Recreational water and industrial discharges are regulated by other federal and state agencies across the country. The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) conducts studies to understand the fate and transport of fecal indicator bacteria in surface and groundwater to aid state and federal partners. A variety of standardized protocols are used to...

Microbial Ecology

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...

Microbial Source Tracking

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...

Silver Lake Nutrient Study

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 and...
