摘要

The prime objective of the field investigation reported was to install a groundwater monitoring network in and below the west arm Nordic tailings in order to determine the general directions of groundwater flow within the tailings, provide a basis for calculation of the groundwater flux into and out of the tailings, and provide a groundwater sampling network. Areas of upward, downward, and horizontal flow were found. In some areas seepage from the tailings enters the sand aquifer beneath the tailings, and in other areas the seepage enters the permeable bedrock. The chemical composition of pore water in the tailings is variable, in some places highly acidic. The general trends in hydraulic head and gradient were delineated, but it was not possible to define groundwater flow paths within and beneath the tailings, or to carry out mass balance studies.
