Distribution of Total Dissolved Solids in the Dunvegan Hydrostratigraphic Unit (gridded data, ASCII format)

This grid represents the distribution of total dissolved solids (TDS) in the Dunvegan hydrostratigraphic unit (HSU). It is a result of a geostatistical model which was constructed using publicly available data from the following sources:

1. Alberta Environment and Parks' (AEP) Alberta Water Well Information Database (AWWID)
2. Formation water chemistry from drillstem test and production fluids from oil and gas wells

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.
