Baseline Environmental Monitoring Program for the Bear Creek Hydraulic Borehole Mining Demonstration Test.

An environmental monitoring program was established to assess the baseline of parameters that may be impacted by a research and development hydraulic borehole mining operation. Two aquifers were identified at the borehole site with the overlying sand aquifer being distinct from the ore sand aquifer on the basis of radiological parameters. Tests to determine the effect of backfilling the boreholes indicated that using overburden from the open pit mining operation would not significantly increase the radiological constituents of the ore sand aquifer. Mining measurements of the radon flux from the borehole indicated that the actual release rate of 0.035 Picocuries per second was several orders of magnitude less than the calculated estimate by the U.S. Environmental Protection Agency. Finally, a gamma survey conducted at the site indicated that the terrestrial component of background radiation was consistent with that in areas near uranium deposits.
