Systems tool new resource to aid groundwater cleanup

RICHLAND, Wash. -- After almost 50 years of nuclear materials production at the 586-square-mile Hanford Site in southeastern Washington, there are more than 700 waste sites with the potential to release contaminants to the soil and groundwater. These sites vary significantly in their inventories of radioactive and chemical contaminants and potential for contaminants to migrate through the soil to the groundwater and the Columbia River. Understanding which waste sites have the most significant impact and the cumulative effect of all the waste sites is important as decision makers investigate options for cleanup and closure of Hanford.

Researchers at the Department of Energy's Pacific Northwest National Laboratory have developed a comprehensive new tool that will provide federal and state regulators with some of the critical information they need to help protect people, the environment and the Columbia River.

The System Assessment Capability, or SAC, is an integrated system of computer models and databases that predicts the movement and fate of contaminants through the vadose zone, the groundwater and to the Columbia River. The vadose zone is the soil above the groundwater. SAC also assesses the impact of contaminants on human health, animals and the environment.

Instead of showing each waste site in isolation as has been done in the past, SAC shows each site in context. "It looks at all the waste sites at Hanford in relationship to each other and how they contribute to future impact," said Bob Bryce, SAC project manager for PNNL. "Using SAC, we can see which waste sites are making the greatest contribution to future impact and clean them up first."

A 14-member team of scientists in fields ranging from civil engineering to zoology created the two sets of computer models that are at the heart of SAC. One set simulates how contaminants move through the environment. The second set estimates risk and impact from those contaminants.
