Early achievement of net-zero greenhouse gas emissions in California brings much larger health benefits than economic cost.

Scientists at the U.S. Department of Energy’s Pacific Northwest National Laboratory have developed and continue to maintain a global database of measurements made of soil-to-atmosphere CO2 flows, termed soil respiration.

Existing techniques to detect pertechnetate in the environment have drawbacks. PNNL’s redox sensor technology uses a gold probe to accurately and efficiently measure low levels of pertechnetate—and possibly other contaminants—in groundwater

A new procedure for estimating sunlight reflection provides insight into feedbacks that affect Arctic warming.

A recent paper published in Water Resources Research found that the spatial variability of subsurface sediments, and seasonal fluctuations in a river’s water level, influences the behavior of a uranium contaminant plume, particularly in ...

Researchers adding water to the surface of alumina measured some surprising results that raise important questions regarding the fundamental reactions that govern chemical transformations of aluminum oxides and hydroxides.

Scientists at the Interfacial Dynamics in Radioactive Environments and Materials (IDREAM) sort out which compounds are present and their concentrations, providing an important new tool with broad applicability.

Tower, aircraft, and satellite observations combined to evaluate weather forecast model.

DOE researchers investigated the role of microbial genetic diversity in two major subsurface biogeochemical processes: nitrification and denitrification.

Nighttime interaction between Bay Area pollution and biogenic isoprene led to efficient formation of secondary organic aerosols.
