Abstract

This map depicts the distribution of hydraulic head in groundwater in the Paskapoo hydrostratigraphic unit (HSU). The map is a result of empirical Bayesian kriging using publicly available water chemistry data from the Alberta Government's Alberta Water Well Information Database (AWWID).  

The distribution of hydraulic head was mapped at a regional scale using many years of data, thus providing a good indication of hydraulic head within the shallow portion of the HSU rather than site specific values. The uncertainty of prediction is depicted on an inset map, which shows the residual values (modelled value minus measured value) plotted at each location to indicate where underprediction or overprediction occurs. Two additional inset maps show the distribution of total dissolved solids, and depth to and vertical thickness of the Paskapoo HSU. The geometry and variable thickness of the Paskapoo HSU are illustrated on schematic cross-sections.
