2. Surface Water Quality Sampling. Quarterly surface water quality sampling from three
stations, SW-1 through SW-3 could not be performed due to insufficient stream flows to
collect samples during the summer, fall, winter and spring sampling periods. However,
sampling of the perched aquifer within the pit was sampled. Results are summarized in
the table below. Note that sampling could not be performed in Q1 2017 since the TSF
was snow covered and the perched aquifer was frozen.
