Summary(Plain Language Summary, not published)
Water resources on the east coast of Vancouver Island are vital to support urban development and agricultural needs, particularly in the Nanaimo Lowlands where population growth has been rapid in the past few decades. To assist the BC Ministry of Forests, Lands, and Natural Resource Operations, and the Regional District of Nanaimo in the characterization of this groundwater resource, the Geological Survey of Canada (GSC) has conducted surface seismic surveys, borehole drilling and core analyses, and borehole geophysical logging to study the geological and hydrogeological properties of the surficial deposits and local bedrock. This Open File contains the results of the downhole geophysical logging conducted by the GSC in one bedrock and four overburden boreholes within the study area. The objective of the surveys was to measure a range of in situ chemical and physical properties of the subsurface materials, ultimately contributing towards the GSC¿s development of a 3D groundwater model of the Nanaimo Lowlands.
