Can Spills from Swine Lagoons Result in Downstream Health Hazards?
Livestock manure spills have been shown to result from events such as equipment failures, over-application of manure to agricultural fields, runoff from open feedlots, storage overflow, accidents with manure transporting equipment, and severe weather. Our specialized teams of hydrologists, chemists, biologists and geologists, in collaboration with Johns Hopkins Bloomberg School of Public Health...
What is the Chemical and Microbial Content of Our Tap Waters?
Safe Drinking Water Act compliance addresses the safety of public-supply water systems. The composition of public-supply drinking water is generally only tested at the treatment facility, and not at the tap in homes and businesses after traveling through the water distribution system. Only lead and copper are tested at a subset of residential and other taps. Testing of water in private wells is...
Are Tumors in Wild Fish Harvested in the Great Lakes Region Related to Contaminants in Water Resources?
Our specialized teams of scientists are working in our laboratories and at field sites around the Great Lakes in collaboration with other federal and state resource agencies to document the prevalence of skin and liver tumors in fish. Tumor prevalence in white suckers ( Catostomus commersonii ), a fish harvested as a food source by local communities, is related to the degree of urbanization in the...
Are Spills Associated with Deep Well Injection of Wastewater from Oil and Gas Operations a Health Hazard?
Our specialized teams of hydrologists, chemists, biologists, and geologists worked together in the New River Gorge National River watershed to answer this question. Wastewater generated in association with oil and gas operations at this site is managed by injection in deep wells designed to safely dispose and contain contaminants in deep geologic formations. Contaminants associated with oil and...
Food Resources Lifecycle Integrated Science Team
The team studies the movement of toxicants and pathogens that could originate from the growing, raising, and processing/manufacturing of plant and animal products through the environment where exposure can occur. This information is used to understand if there are adverse effects upon exposure and to develop decision tools to protect health.
Bioactive Chemicals Research Laboratory
The Bioactive Chemicals Research Laboratory applies a collaborative transdisciplinary approach to conduct research to minimize the risk to human and aquatic organism health from exposure to contaminants in water supplies.
Michigan Bacteriological Research Laboratory
Microbiologists at the Michigan Bacteriological Research Laboratory (MI-BaRL) use a wide array of traditional and modern molecular approaches to evaluate microbial pathogens and antimicrobial resistance pathways in the environment.
Systematic Approach to Understanding Tree Swallow Health in the Great Lakes Region—Science to Inform Restoration
Four papers by U.S. Geological Survey (USGS) scientists document tree swallow ( Tachycineta bicolor ) chemical exposure, physiological responses, and reproductive success in the Great Lakes region. These studies were designed to understand if there are health threats to swallows from contaminant exposure, and to provide resource managers with information about the actual as opposed to the...
Fishing and Hunting Integrated Science Team
The Fishing and Hunting integrated science team focuses on contaminant and pathogen exposures in the environment that could impact the presence and vitality of fish and wildlife populations that drive commercial, recreational and subsistence activities such as hunting and fishing. If actual risks are identified this project will inform how to economically and effectively minimize risk by providing...
Scientists Identify Processes that Affect Fish Mercury Concentrations in Estuarine Wetlands
In a study designed to help resource managers when considering mercury exposure risk, scientists determined that sulfur cycling—a process closely related to mercury methylation rates—and ecological conditions that influence exposure are important factors affecting fish mercury concentrations in estuarine wetlands.
Selected Pharmaceuticals Not Likely to Persist in Wild Fish: Results of Uptake and Elimination Testing
Laboratory study shows that both uptake and elimination of selected pharmaceuticals within bluegill tissues is rapid indicating that persistence in bluegills in the environment is likely to be low except in those fish that reside downstream from a consistent, substantial, contaminant source.
Endocrine Active Chemical Screening Tests Optimized to Improve Precision, Accuracy, and Timeliness
Scientists optimized existing endocrine active chemical screening tests to improve their precision, accuracy, and ability to screen more samples in a shorter time-frame. The optimization was done to more rapidly obtain results from the bioassays so that research on the risks of endocrine active chemical exposure can proceed more rapidly.
