This data release contains water chemistry data used to create a total dissolved solids (TDS) map of the Wapiti / Belly River hydrostratigraphic unit (HSU) as part of the Alberta Geological Survey’s (AGS) Provincial Groundwater Inventory Program. It also contains the calculated difference (residual) between the modelled distribution of TDS and measured values from wells. The source datasets are water well chemistry data from Alberta Environment and Parks' Alberta Water Well Information Database (AWWID) and formation water chemistry data from oil and gas well drillstem tests (DSTs) and production fluids.
Data have been processed, relevant records selected, and outliers removed to compile this dataset.
