Abstract
An abandoned waste impoundment located within a portion of the Bunker Hill Superfund Site constitutes a field research area for studying the feasibility of recovering heavy metals in-situ from unsaturated mine and mill wastes. A prototype in-situ leaching cell has been evaluated using liquid-phase tracer tests and other hydrogeologic tests prior to introducing a lixiviant. The results of the tests suggest that: 1) the cell can be operated excursion-free with a low-density lixiviant at an injection/withdrawal rate of approximately 0.32 Vs; and (2) each hydrogeologic unit is highly heterogeneous at the different scales studied.
