This grid represents the distribution of total dissolved solids (TDS) in the Keg River / Winnipegosis hydrostratigraphic unit (HSU). It is a result of a geostatistical model which was constructed using publicly available formation water chemistry data from oil and gas well drillstem tests (DST) and production fluids, as well as industry monitoring wells accessed through environmental impact assessment reports.
The TDS surface was mapped at a regional scale using many years of data, thus providing a good indication of regional water chemistry within the unit rather than site-specific values.
