Objective(s): This research study is designed to investigate the processes related to water quality draining from country rock stockpiles that are located in areas of continuous permafrost.
Project Description: This research study is designed to investigate the processes related to water quality draining from country rock stockpiles that are located in areas of continuous permafrost. Three country rock stockpiles have been constructed with instruments including: thermistors, time domain reflection (TDR) probes measuring internal pile water content and movement, and air pressure transducers (all connected to dataloggers), plus soil-water solution samplers (SWSS), air permeability probes, thermal conductivity access ports to measure thermal conductivity properties, gas sampling ports to obtain oxygen and carbon dioxide levels, and microbiology access conduit and pyrite growth media (all sampled manually). The test piles were constructed on an impermeable HDPE liner with 12 lysimters (water collection boxes) on the liner to collect water samples. All water from the base is discharged through a series of flow-through cells to measure pH and conductivity, and collect water samples. Water is then directed to rain gauges/flow meters to measure flow. Reports are disseminated through the Geoscience Forum in Yellowknife, annual reports, and conference presentations. EMAB site visits include a brief discussion of test piles. Research will be included in Masters and/or PhD theses. Fieldwork will be conducted from April 01 to December 31, 2008 at Diavik Diamond Mine, Lac de Gras Mine Site (64"30'N, 110"30'W).
