PFAS Transport, Exposure, and Effects

The team is determining the movement and behavior of per- and poly-fluoroalkyl substances (PFAS) from their sources in the environment, as they move through exposure pathways in ecosystems including watersheds and aquifers, their incorporation into food webs, and molecular to population scale effects on fish and wildlife. These studies are accomplished at a variety of spatial scales from...

No Evidence of Toxicity to Birds Ingesting Neonicotinoid-Coated Wheat Seeds During Controlled Laboratory Study

Scientists determined what happens to the neonicotinoid insecticide, imidacloprid, on coated wheat seeds once ingested by Japanese quail (Coturnix japonica)—a model species for free-range, seed-eating, upland game birds. Imidacloprid was found to be rapidly adsorbed, metabolized, and excreted, and resulted in no overt signs of toxicity during a controlled laboratory study.

Novel Approach Improves Understanding of Virus Occurrence in Drinking Water

Waterborne viruses, one of the leading causes of gastrointestinal illnesses, were measured in United States drinking water sources and finished water. Scientists used a combination of measurement and statistical techniques to overcome limitations to quantifying these viruses, thus offering an enhanced method for virus monitoring.

Can There be Unintended Benefits when Wastewater Treatment Infrastructure is Upgraded?

Science from the U.S. Geological Survey (USGS) and other entities has shown that a mixture of natural and synthetic estrogens and other similar chemicals are discharged from wastewater treatment plants (WWTPs) to streams and rivers.

USGS and University of Colorado hydrologists, chemists, geologists, and biologists studied the chemistry and biology of Boulder Creek downstream of Boulder ...

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...

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...

Disaster Science

Natural (coastal storms, wildfires, floods) and human-induced (structural failures, building collapse, oil, and/or chemical spills) disasters occur every year in the United States. Minimizing loss of human life and damages to personal property and infrastructure is the focus of most disaster response and preparedness activities by federal, state, and local communities. However, the potential...
