Uranium removal from groundwater via in situ biostimulation: Field-scale modeling of transport and biological processes.
During 2002 and 2003, bioremediation experiments in the unconfined aquifer of the Old Rifle UMTRA field site in western Colorado provided evidence for the immobilization of hexavalent uranium in… Expand

Removal of As, Mn, Mo, Se, U, V and Zn from groundwater by zero-valent iron in a passive treatment cell: reaction progress modeling.
Three treatment cells were operated at a site near Durango, CO. One treatment cell operated for more than 3 years. The treatment cells were used for passive removal of contamination from groundwater… Expand

Uranium precipitation in a permeable reactive barrier by progressive irreversible dissolution of zerovalent iron.
A permeable reactive barrier (PRB) containing zerovalent iron [Fe(O)] was installed at a former uranium milling site in Monticello, UT. A large-scale column experiment was conducted at the site to… Expand

Early breakthrough of molybdenum and uranium in a permeable reactive barrier.
A permeable reactive barrier (PRB) using zerovalent iron (ZVI) was installed at a site near Cañon City, CO, to treat molybdenum (Mo) and uranium (U) in groundwater. The PRB initially decreased Mo… Expand

The effects of offering a range of forage and concentrate supplements on milk production and dry matter intake of grazing dairy cows
An experiment was undertaken to examine the effect of supplement type on herbage intake, total dry matter (DM) intake, animal performance and nitrogen utilization with grazing dairy cows. Twenty-four… Expand
