Digital Data 2022-0019
This grid represents the distribution of total dissolved solids (TDS) in the Horseshoe Canyon / St. Mary River hydrostratigraphic unit (HSU). It is a result of a geostatistical model which was constructed using publicly available water chemistry data from the following sources:
- Alberta Environment and Parks' (AEP) Alberta Water Well Information Database (AWWID)
- Alberta Health Services (AHS)
- Alberta Energy Research Institute (AERI)
- Baseline Water Well Test Database (BWWT)
- Data submissions by industry as required by Alberta Energy Regulator (AER) Directive 044: Requirements for Surveillance of Water Production in Hydrocarbon Wells Completed Above the Base of Groundwater Protection
- Oil and gas well drillstem tests (DSTs) and production fluids.
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.
