Per-and Polyfluoroalkyl Substances (PFAS) Integrated Science Team

Per- and poly-fluoroalkyl substances (PFASs) are a large group of synthetic chemicals utilized for diverse applications including non-stick coatings, industrial lubricants, fire retardants in clothing and home goods, and as fire suppressors in firefighting foams. Due to the wide variety of PFAS uses and their resistance to breakdown, they have been detected in surface and groundwater resources...

Technique Used to Distinguish Natural Background from Human-Caused Enrichment of Trace Elements in Soils

Human activities can enrich toxic trace elements like uranium and arsenic in the environment, but these elements also are from natural sources and occur at background levels. Scientists utilized a technique that identifies the background and the elemental fingerprint of human-caused enrichment and tested the new technique on data collected near uranium mines in Arizona.

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 ...

Food Resources Science Team

The team studies the movement of toxicants and pathogens associated with food production through watersheds and aquifers, to water resources where exposure can occur. That information is used to understand if there are adverse effects upon exposure and to develop decision tools to protect health.

Minerals Science Team

The Minerals Integrated Science Team focuses on contaminant exposures in the environment that might originate from mineral resource activities including, transportation, storage, extraction and waste management. Perceived health risks to humans and other organisms will be distinguished from actual risks, if any. If actual risks are identified this Team will inform how to...
