The Geological Survey of Canada (GSC) is investigating the hydrogeology of the Spiritwood buried valley aquifer in southwestern Manitoba as part of its Groundwater Geosciences Program. This Open File reports on a drilling program conducted in November 2010 in which one shallow and one
intermediate depth piezometer were installed within separate boreholes at each of three sites near Killarney, Manitoba to complement existing deep wells monitored by Manitoba Conservation and Water Stewardship (Government of Manitoba, Ministry of CWS). Boreholes were advanced without drilling fluids
by the cable tool method and by driving core tubes which allowed for accurate borehole logging and the collection of sample cores at selected depths. This Open File includes the geological logs of the boreholes, the piezometer construction details and the geotechnical data measured on sampled core.
Geotechnical analyses included measurement of approximate shear strength using a pocket penetrometer (n=21), grain size distribution (n=8), gravimetric water content (n=91), and wet bulk density (n=22) from which dry bulk density (n=22) and volumetric water content (n=22) were calculated and
porosity (n=22) estimated.
The drilling program was a collaborative effort between the Agri-Environmental Services Branch (AESB) of Agriculture and Agri-Food Canada (AAFC) and the Geological Survey of Canada of Natural Resources Canada (NRCan).
