Summary(Plain Language Summary, not published)
A relatively thick and extensive succession of late Pleistocene proglacial, glacial and interstadial sediments occurs in the Strait of Georgia in British Columbia (and Puget Sound in Washington. All of these units form either regional aquifers, or aquitards, hence understanding the spatial heterogeneity and lithochemistry are of high interest due to increasing groundwater issues in this area.To resolve this knowledge gap the Geological Survey of Canada in collaboration with the Regional District of Nanaimo, British Columbia, has completed a chemostratigraphic study of 2 boreholes (~130 m deep) approximately 20 km apart, using a portable X-ray fluorescence spectrometer and multivariate statistical methods.
