U.S. Geological Survey Per- and Polyfluoroalkyl Substances Science Strategy Identifies Science Gaps and Opportunities

USGS recently (2022) released a strategic vision document that identifies science gaps and opportunities for per- and polyfluoroalkyl substances (PFAS) monitoring, assessment, and research activities (sampling protocols and analytical methods, environmental sources and source apportionment, environmental occurrence, environmental fate and transport, human and wildlife exposure routes...

Advanced PFAS Measurement Methods

Environmental Health Program scientists, in collaboration with other USGS scientists, are developing complementary field and laboratory methods and capabilities to detect and quantify a range of target and nontarget per- and polyfluoroalkyl substances (PFAS) and indicator compounds at low levels (parts per trillion) in a variety of environmental matrices. The PFAS Integrated Science Team is...

Science to Understand Low-Level Exposures to Neonicotinoid Pesticides, their Metabolites, and Chlorinated Byproducts in Drinking Water

Scientists reported the discovery of three neonicotinoid pesticides in drinking water and their potential for transformation and removal during water treatment. The research provides new insights into the persistence of neonicotinoids and their potential for transformation during water treatment and distribution, while also identifying granulated activated carbon as a potentially effective...

Environmental Health Program Drinking Water Science

Drinking water in the United States rarely is tested for contaminants and pathogens at the tap, where human exposure can occur. In this special issue, we present the science to help understand contaminants and pathogens in drinking water at business and residential taps.

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 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...
