Abstract

Two cores were drilled in the Basal Paskapoo aquifer at Ponoka to study the relation of geology to hydrology in the formation. Permeability, porosity and grain size analyses of the cores were studied in the laboratory, and it was found that the horizontal permeability in No. 2 core is much greater than in No. 1. This was due in part to better sorting as shown by the grain size analysis. These two cores are only 180 feet apart which points out that the formation is not uniform in character. The results were confirmed by pump tests which showed that the transmissibility in No. 2 core is much higher than in No. 1. This confirms the dependence of the hydrology on the geology of the formation. The porosity was the same for the two cores. The leakage coefficient in the aquifer was also calculated from pump tests using a method developed by Hantush. Study of the chemical analysis of ground water in the area showed that there are three types of water. This separation was based mainly on the ratio of hardness to sulphate and other constituents. The field location of these three types show relation to recharge and discharge areas. Special studies were carried out including the construction of a vertical variability map of the bedrock sandstone in the area, and points of high and low ground water potential were outlined. It is shown that the centre of gravity map can be used to outline areas of high and low transmissibilities. Thornthwaite's formula was used to study the climatology of the area and tentative conclusions on the amount of evapotranspiration, runoff, and recharge were reached but are subject to considerable doubt.
