The hydrogeological characteristics of the Upper Cretaceous De Courcy Formation (Nanaimo Group), from a subsurface core, groundwater observation well, Cedar, British Columbia / [by] A.P. Hambin and T.... : M183-2/7628E-PDF

As part of the investigation of the groundwater potential of the Nanaimo Group bedrock units, a drill core 112.5 m long was obtained from an Observation Well near the village of Cedar on Vancouver Island. The entire length of the core comprises the sandstone-dominated (potential aquifer zone) De Courcy Formation, and is characterized by thick bedded, medium to coarse grained sandstone (65% of core) with interbedded units of sandy siltstone. Sandstones have decent porosity and permeability and may form subsurface aquifers, whereas siltstones have lesser porosity and permeability and may form intervening barriers to groundwater flow. More importantly, the characteristics displayed in this core provide analogies for deeper and more widespread potential aquifer zones within the Nanaimo Group (Comox, Extension, Protection formations), for which we have no subsurface data.
