The scope of this study is to map the hydraulic head and water chemistry distributions in all the major (non-Quaternary) aquifers in the study area. The aquifers to be evaluated were the Grand Rapids, Clearwater, Wabiskaw/Upper McMurray and Basal McMurray/Devonian. The dataset used in this evaluation consists of pressures and water analyses from wells in the area. 2048 pressures were acquired from DSTs, AOF well tests and several vibrating wire piezometer instruments. 271 water analysis were acquires from the GeoFluids database of oilfield fluid samples.
