Core Technology Team

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...

The Environmental Health Program features a Unified Core Technology Team comprised of multiple laboratories with specialized expertise that support the overall program research assessing actual and perceived risks from environmental contaminants and pathogens. Individual Core Technology Teams work closely with the Integrated Science Teams to ensure current and emerging techniques are being used to...

About the Laboratory The Environmental Health Program collaborates with scientists at the Organic Geochemistry Research Laboratory (OGRL) in Lawrence, Kansas, to develop and employ targeted and non-targeted analytical methods for identification and quantitation of known and understudied algal/cyanobacterial toxins. The laboratory contructed in 2019 is a 2,500 square foot modern laboratory facility...

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...

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...

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.

Harmful algal blooms (HABs) are a significant environmental concern due to their potential effects on health, ecosystems, and economies. Algal toxins, which are toxic compounds produced by certain species of cyanobacteria and algae, are commonly linked to these blooms. It's important to note that algal toxins can still be present even when a bloom is not visible, highlighting the need for ongoing...

Per- and polyfluoroalkyl substances (PFAS) are a group of over 14,000 different man-made compounds that are widely used in various industrial and consumer products and linked to various health issues. Perfluorooctanesulfonic acid (PFOS) is a persistent synthetic chemical within the PFAS group, recognized for its widespread use and persistence in the environment. The U.S. Geological Survey is...

USGS scientists have advanced methods to measure bacterial activity in environmental waters. Their research showed that when bacteria naturally in the water are exposed to substances like pharmaceuticals, herbicides, and antimicrobials, their normal functions are disrupted. This finding suggests that monitoring bacterial activity could provide early warnings about potential problems with water...

Stormwater and road runoff are recognized forms of pollution that can contain chemicals harmful to fish and other aquatic animals. This includes 6PPD-quinone, the oxidized form of the chemical compound 6PPD that is used to prevent tires from degrading and cracking, ensuring driver safety. As 6PPD-quinone sheds from tires during normal wear it can enter streams in stormwater runoff.

In October of 2024, USGS Scientist’s published a study where they created a model to predict PFAS occurrence in groundwater at the depths of drinking water supplies. This model can help guide our partners to sample areas where PFAS in drinking water could be an issue for the public.

The Per- and Polyfluoroalkyl Substance (PFAS) Core Technology Team (CTT) within the Environmental Health Program partners with external and internal stakeholders to develop and apply analytical methods for measuring PFAS in complex matrices, addressing environmental health issues related to transport, distribution, fate, effects, and exposure.
