Lake monitoring and research

Studying lakes provides an improved understanding of lake ecosystem dynamics and valuable information that helps lead to sound lake-management policies. The USGS collects hydrologic data in lake settings, studies water and nutrient budget development, conducts source-loading analysis, explores groundwater interactions, and performs lake water-quality modeling.

Groundwater monitoring and research

Groundwater is an important water resource. The USGS collects information on the quality and quantity of groundwater and conducts advanced modeling of groundwater flow and groundwater/surface-water systems. The USGS also evaluates the effects of water-use, land-use, and climate change on groundwater, surface-water, and the ecosystems that rely on them.

Ecoflows: Developing Indices of Streamflow Alteration

The Minnesota Pollution Control Agency (MPCA) lists streamflow alteration as a key stressor on aquatic life in many watersheds. However, the MPCA currently does not have the information needed to quantitatively associate metrics from Index of Biological Integrity (IBI) surveys with metrics of streamflow alteration.  We are using USGS streamgage data and MPCA IBI data to develop relations...

Edge-of-field monitoring

Edge-of-field monitoring focuses on identifying and reducing agricultural sources of excess nutrients which can threaten the health of streams, rivers, and lakes. Edge-of-field monitoring assesses the quantity and quality of agricultural runoff and evaluates the effectiveness of conservation practices that aim to reduce nutrient loss.

Chemicals of Concern in the Great Lakes Basin

The Great Lakes are an important freshwater source of drinking water, fisheries, and habitat. Chemicals of concern are introduced to the environment by human activities, but resulting ecological consequences are little understood. With federal and University partners, we are characterizing the presence of contaminants and potential effects to fish in Great Lakes tributaries.

Environmental Effects of Agricultural Practices

As agricultural land in the Minnesota River Basin is retired, tile drains are removed or broken and riparian corridors are planted to reduce runoff. Early studies saw decreased sediment and nitrogen and improved biological indicators but no significant changes in phosphorus. This project continues to investigate the linkages...

Bacterial Pathogens

The U.S. Geological Survey (USGS) Michigan Bacteriological Research Laboratory (MI-BaRL) studies the source, occurrence, and distribution of the bacterial pathogens Shiga-toxin producing E. coli (STEC), Salmonella, Shigella, Campylobacter, Enterococcus, and Staphylococcus and the relation of occurrence of pathogens with fecal indicator bacteria, land-use, season, hydrology, geology, weather...

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...

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 (...

Using optical sensors to detect sewage contamination in the Great Lakes

In the Great Lakes, large volumes of sewage never make it to wastewater treatment plants due to illicit discharges and leaking sewer infrastructure, but contamination can be difficult to detect. This study will define the utility and practicality of using optical sensors to identify the sources and timing of sewage contamination in surface water and storm sewers in real-time field settings....
