Hydrogeology
Water well locations, aquifer vulnerability mapping, and groundwater data that characterize Alberta's subsurface water resources.

Government of Alberta
The Alberta Water Well Information Database (AWWID) contains drilling reports for over 500,000 licensed water wells across the province, maintained by the Government of Alberta and updated daily. Each record includes well depth, casing dimensions, drilling date, driller name, well use classification, well status, ground-level elevation, and location coordinates.
- •Identifying nearby domestic and municipal water supply wells that may be impacted by contaminated sites during Phase 1 and Phase 2 ESAs.
- •Reviewing historical well logs to characterize subsurface stratigraphy and groundwater conditions in areas with limited borehole data.
- •Assessing baseline groundwater use patterns and well density to evaluate receptor sensitivity for risk assessments.
- •Locating existing monitoring infrastructure that could supplement site investigation programs.
Displayed as point features color-coded by well use type (domestic, municipal, industrial, etc.) with filtering by well use and status. The Distance Calculator finds the nearest water wells to any point, and individual well records can be inspected to view depth, driller, date, and status.
Base of Groundwater Protection
Government of Alberta
Aquifer vulnerability index dataset published by the Government of Alberta, assessing groundwater contamination risk across the province. The index evaluates depth to aquifer and the types of geological materials above each aquifer to determine vulnerability ratings -- shallower aquifers with permeable overlying materials receive higher scores than deeper formations protected by impervious layers.
- •Prioritizing contaminated sites for remediation based on groundwater vulnerability and receptor exposure risk.
- •Designing appropriate monitoring well networks with consideration for aquifer sensitivity.
- •Supporting regulatory compliance by identifying areas requiring enhanced groundwater protection under Alberta Tier 1/Tier 2 guidelines.
- •Evaluating suitability of land parcels for waste disposal, storage facilities, or industrial development based on groundwater risk.

How consultants use these layers
- 1Identifying domestic water wells within the required notification radius of a contaminated site.
- 2Assessing aquifer vulnerability to determine groundwater sensitivity and appropriate remediation targets.
- 3Reviewing water well drilling records for hydrogeological context (depth to water, geological formations).
