PNNL empowers, leads and promises to make the world a safer, cleaner and better place. That commitment led our scientists to explore how contaminants move in soil. The region between the soil surface and above the water table is of great interest to PNNL researchers, because it can act as a source for groundwater contamination—contaminants of concern include organic materials (oil), metals, and radionuclides. Here scientists imaged air and water distribution in idealized sediment to evaluate their impact on how contaminants travel underground.
