The USGS is investigating the effects of 6PPD-quinone (6PPDQ), a harmful contaminant found in urban stormwater runoff, on fish and wildlife health, particularly in salmonids. Recent studies have shown that 6PPDQ poses acute toxicity risks, especially to coho salmon, with sensitivity varying by life stage. New research evaluated the lethal and sublethal impacts of 6PPDQ exposure on coastal...

In recent years, per- and polyfluoroalkyl substances (PFAS), have gained attention for their environmental presence; however, the term "ubiquitous" used to describe them can be misleading. USGS scientists push to use more precise language such as "widespread" and “commonly detected” to avoid confusion and misinformation. This distinction is crucial for understanding the actual occurrence of PFAS...

The Potomac River is a major watershed in the eastern United States that serves as a crucial water supply for millions of people. USGS researchers conducted a comprehensive investigation to identify the contributions of municipal and industrial wastewater treatment plant effluent to the levels of per-and polyfluoroalkyl substances (PFAS) in the Potomac River. This study included measuring PFAS...

Energy is essential to modern life, and accessing it involves a complex lifecycle, from resource discovery to extraction, use, and eventual remediation and reclamation. The USGS Ecosystems Mission Area supports this process by conducting research and providing scientific insights to guide decision-making at each stage. By collaborating with resource management agencies and stakeholders, we analyze...

The USGS Environmental Health Program seeks to understand how environmental factors, especially contaminants and pathogens, influence human health and ecosystems. It focuses on studying the distribution and effects of toxic substances, environmental stressors, and their pathways. The program prioritizes collaboration with State, Federal and local governments; Tribes; non-government organizations...

Clean water is essential for both environmental health and human safety, but many everyday products and activities can contribute to water pollution including contaminants such as microplastics, harmful chemicals such as pharmaceuticals and pesticides, and antibiotic resistance genes. A recent USGS study in Iowa investigated pollutants in streams, including stream sediment and biota, to determine...

The USGS Environmental Health (EH) Program research where per- and polyfluoroalkyl substances PFAS are found, how they move and change in the environment, how they might affect both ecosystems and human health, and ways to reduce their impact. The three teams focusing on these issues within the EH Program include: 1) the PFAS Integrated Science Team, 2) the PFAS Core Technology Team, and 3) the...

The growing concern of finding per- and polyfluoroalkyl substances (PFAS) in drinking water has led USGS scientists to conduct more comprehensive analyses that encompass an extensive list of compounds that can be found in drinking water. These analyses will develop a more complete drinking water contaminant list that managers can use to make more informed public health decisions.

Produced water is a complex waste byproduct from oil and gas development that can be repurposed for beneficial uses. Understanding its applications, how it moves through the environment, and its potential effects on human health is essential. USGS researchers, in collaboration with Health Effects Institute (HEI) Energy, reviewed and analyzed existing literature to identify knowledge gaps about...

Energy development is critical to American energy independence and provides economic benefits to local communities. Scientific information is needed to aid in the sustainable development of energy resources. Sustainable energy development can include strategies for protecting environmental health and ecological services that benefit local communities. The USGS Environmental Health Program, Energy...

Critical minerals are essential to the Nation’s economy and security. Demand for critical minerals is increasing, and it is essential to balance the societal need for these minerals with efforts to understand the effects of mining on other natural resources and to develop techniques to minimize these effects. The USGS Minerals Resources Life Cycle Integrated Science Team (IST) focuses on the life...

The Environmental Health Program integrates multidisciplinary research to tackle the environmental challenges that impact the nation's natural resource assets. By providing comprehensive research and data, the program assesses both actual and perceived risks associated with environmental contaminants and pathogens while supporting a variety of uses of our natural resources.
