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

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

1. The Alberta Government's Alberta Water Well Information Database (AWWID)
2. A previous Alberta Geological Survey water sampling project reported in AGS Special Report 81

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.
