MONITORING IN SITU BIOREMEDIATION AT THE RIFLE, COLORADO IFRC SITE WITH NUCLEAR MAGNETIC RESONANCE AND MAGNETIC SUSCEPTIBILITY MEASUREMENTS

摘要

Nuclear magnetic resonance (NMR) and magnetic susceptibility (MS) borehole logging measurements were collected at the Rifle Integrated Field Research Challenge (IFRC) site. The Rifle IFRC site is located at a former uranium ore-processing facility in Rifle, Colorado. Although removed from the site by 1996, leachate from spent mill tailings has resulted in residual uranium contamination of both groundwater and sediments within the local aquifer. Since 2002, research at the site has primarily focused on quantifying uranium mobility associated with stimulated biogeochemical processes.
