Nationwide Occurrence

A National-scale approach is used to examine and analyze per- and polyfluoroalkyl substances (PFAS) prevalence and magnitude in watersheds and aquifers. As an initial step to fill known science gaps in the understanding of human and wildlife exposure, the team will provide a snapshot of PFAS in drinking water paired with bioaccumulation in fish and wildlife near known or suspected sources of...

Is Uranium in Water Resources near the Grand Canyon a Health Hazard?

The public is concerned that uranium in natural geologic formations, mine tailings, dusts, water, and other geologic materials can pose a health hazard to humans and wildlife. Our specialized teams of hydrologists, chemists, and geologists working together at a field site in the Grand Canyon region of the United States have shown: Elevated uranium concentrations (above the drinking water standard)...

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.

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...
