Drinking Water Source Areas for British Columbia Water Systems

Polygon features delineating potential source areas for drinking water systems in British Columbia, as defined by the Drinking Water Protection Act. This dataset, published by the Government of British Columbia, is one of three related datasets on drinking water sources and was last updated in April 2026. Source areas likely represent entire aquifers or upstream watersheds, though hydrologic connectivity is not guaranteed.

Use Cases

• Mapping potential groundwater recharge zones based on aquifer extents.
• Identifying upstream watersheds for surface water intake protection based on watershed polygons.
• Relating source areas to specific intakes or wellheads based on unique Source Area IDs.
• Assessing broad-scale risks to drinking water systems based on geographic source area features.

Strengths

• Data is part of a structured series of three related datasets for drinking water sources.
• Polygons include unique Source Area IDs for relational joins with other datasets.
• Last updated date is explicitly provided as 2026-04-22.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The description notes source areas are broad and do not guarantee hydrologic connectivity has been analyzed.
