Donor-dependent extent of uranium reduction for bioremediation of contaminated sediment microcosms
Bioremediation of uranium was investigated in microcosm experiments containing contaminated sediments from Oak Ridge, Tennessee to explore the importance of electron donor selection for uranium reduction rate and extent. In these experiments, all of the electron donors, including ethanol, glucose, methanol, and methanol with added humic acids, stimulated the reduction and immobilization of ...

Effect of Suspended Uncontaminated Sediment on POP Release
The transport and fate of persistent organic pollutants (POPs) during resuspension events were investigated using a batch mixing technique. This technique allowed for the determination of sorption and desorption kinetics under more realistic mixing conditions than those used in previous investigations. It was demonstrated that sorption follows second-order kinetics that are dependent on both POP ...

Great Lakes restoration is under threat. Here’s why that matters
Degraded by decades of pollution, the North American Great Lakes are finding new life through cleanup efforts now threatened by proposed federal budget cuts. The St. Louis River, which flows into Lake Superior — the greatest of North America’s Great Lakes — has a long and turbulent history. Once a portal for Native American trade and a garden for wild rice, these waters that ...

Geotube Dewatering Technology is Sound Application for Remediation of Fox River Cleanup Site - Case Study
Technology Allows Processing of Large Volumes While Retaining Impurities and Making Collection and Disposal Easier. Environmental remediation projects are often complicated, challenging—and huge. In fact, a number of remediation jobs that should be done have been delayed because there was no economical way of getting them accomplished. But that could be changing, thanks to a remarkably ...
