Sophisticated monitoring array to address mystery of uranium plume
Date:9/17/2008

RICHLAND, Wash. Scientists have puzzled for years about why uranium contamination in groundwater continues to exceed drinking water standards in an area located at the south end of the Hanford Site. The Department of Energy wants answers to why the uranium persists.

Now, an innovative system has been installed for field experiments to better understand this complex site and to support future cleanup decisions. The site is one of three Integrated Field Research Challenge, or IFRC, locations supported by DOE's Office of Science to investigate fundamental science issues important to contaminant transport and groundwater remediation. New insights may offer scientific advances in environmental cleanup beyond Hanford.

Scientists at DOE's Pacific Northwest National Laboratory are closer to having answers to the mystery with a unique subsurface experimental system containing nearly three dozen monitoring wells equipped with sophisticated instrumentation. The entire subsurface surrounding the wells will be comprehensively characterized to enable a complete accounting of the processes that occur beneath the surface that contribute to the persistent groundwater contamination.

"The plume has baffled researchers for more than a decade," said PNNL Project Manager John Zachara, who leads a team of experts in subsurface geochemistry, hydrology and microbiology. "But we believe this new approach will allow us to better understand the sources and migration behavior of uranium in the subsurface."

The project promises to provide one of the most comprehensive evaluations of the complex 300 Area subsurface along the river in more than 40 years.

Positioned like a triangular chessboard within an approximate 100-meter plot of contaminated ground, the array of 35 monitoring wells is near the location where large volumes of contaminated wastewater were disposed. The waste originated from nuclear fuel fabrication facilities
