This grid represents the distribution of total dissolved solids (TDS) in the Wapiti / Belly River hydrostratigraphic unit (HSU). It is a result of a geostatistical model that was constructed using publicly-available data from Alberta Environment and Parks' (AEP) Alberta Water Well Information Database (AWWID) and formation water chemistry data from drillstem test and production fluids from oil and gas wells (see AGS dataset DIG 2017-0026).
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.
