Advanced Capabilities and Research

About the Research The Michigan Bacteriological Research Laboratory (MI-BaRL) Core Technology Team (CTT) as part of the Environmental Health Program uses a wide array of traditional and modern molecular approaches to evaluate microbial pathogens and antimicrobial resistance pathways in the environment. The scientists use these approaches to advance the understanding of how environmental...

The GLRI Urban Stormwater Monitoring effort brings together the expertise of the USGS with local and national partners to assess the ability of green infrastructure to reduce stormwater runoff in Great Lakes urban areas.

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.

The USGS Mercury Research Lab is a national leader in advancing mercury research and science, specializing in low-level mercury speciation and isotope analysis and mercury-source fingerprinting. The MRL leads national cutting-edge collaborative studies, including state-of-the-art sample analysis, methods development for field and lab procedures, and data interpretation and dissemination.

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...

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 ( MRSA ), and Klebsiella and E. coli resistant to third...

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.

Fluvial geomorphology studies provide an understanding of the physical processes responsible for shaping the character of streams and their riparian zones across both glaciatied and unglaciated regions of Wisconsin and the midwestern U.S.

The TC Chamberlin Modeling Center provides one-stop access to advanced computing so no project is limited by a lack of computer power. The Center can provide hardware access, assistance with migration and implementation, and training. We also develop, test, and disseminate state-of-the-art computational and analytical techniques and tools so models can be more effectively used in decision-making.

Many control options for sediments and associated contaminants in storm-water runoff from urban areas rely on settling of solids. This study characterizes particle-size distributions in urban storm-water runoff from specific source areas and land-use categories, with the hopes of assisting watershed managers and engineers design better control devices for reducing sediment in urban runoff.

The goals of this study were to quantify pathogen concentrations in water at three Lake Michigan beaches, identify environmental factors that influence pathogen occurrence and variability, and to estimate health risks for recreational swimmers.

In response to decreasing water levels in the Great Lakes, especially Lake Michigan and Lake Huron, the International Upper Great Lakes Study (IUGLS) asked USGS to continuously measure flows in the connecting channels of St. Marys, St. Clair, and Detroit Rivers, and Water Survey Canada (WSC) to measure flows of Niagara River. To accommodate the effects of variable backwater and the unsteadiness of...
