Several application methods are available for enzymatic reduction and precipitation of uranium. These include bioreactors, placement of the microorganisms on solid substrates for filtration, or placement in groundwater to create precipitation zones through which the contaminated groundwater migrates.

Hetal Contaminants in the Environment. From the perspective of environmental remediation, the focus of separation science should be on the metals currently being regulated from the standpoint of groundwater protection. This is not a hard and fast rule, as there are a number of situations (e.g., specific spills, waste-stream-specific toxins, etc.) where the focus will be on the removal of a specific hazardous metal compound or substance for which standards have not been set. For example, there is currently much emphasis within the DOE on uranium contamination at the Fernald Site in Ohio. 

Here, we use the Bear Creek Uranium example discussed in 6.2 to calculate the acidity of contaminated groundwater and tailings fluids. If the total acidity of groundwater and contaminated sediments, as well as the neutralization capacity of the aquifer matrix are known, the distance that the acid plume will migrate can be estimated based on mass balance.

Subsurface contamination by uranium wastes and contaminant speciation during transport from a wastewater pond (originating from a plutonium production plant) to groundwater were studied by Catalano et al. (2006). Land disposal of basic sodium aluminates and acidic U(VI)-Cn(ll) and their redistribution in the vadose zone resulted in development of a groundwater nraninm plume. The solid phase speciation of nraninm from the base of the pond, throngh the subsurface, to the... 

Fluor Daniel GTl, Inc. (now part of the IT Corporation), has developed in situ geochemical fixation technology to immobilize metallic contaminants in soil, sediment, sludge, and groundwater. The technology uses a site- and contaminant-specific combination of reagents to convert ionic contaminants to less soluble forms. In situ geochemical fixation has been used to remediate sites contaminated with chromium, uranium, molybdenum, and copper. 

VOCs), uranium, and heavy metals. There has been extensive research on various materials for use in PRBs. Metal-based PRBs are common because the reactive material is commercially available at low costs and has been effective on a variety of contaminants. Metal-based PRBs act as selective filters to contaminants and are being developed in response to the need for effective, low-cost technologies to remediate contaminated subsurface environments. The barriers are permeable to water and nontargeted groundwater constituents and impermeable or destructive to the target contaminant(s).
