Relative Seawater Intrusion Vulnerability for Nova Scotia Coastal Aquifers

A GIS-based approach evaluates the relative vulnerability of bedrock coastal aquifers in Nova Scotia's unserviced areas. The method uses provincial spatial datasets like digital elevation models, civic address points, and well logs. The Government of Nova Scotia published this dataset, which was last updated on April 17, 2026.

Use Cases

• Model seawater intrusion risk based on distance to the coast criteria
• Assess aquifer vulnerability based on land slope and static water level
• Evaluate groundwater sustainability based on development density and non-residential groundwater use

Strengths

• Derived from multiple provincial spatial datasets including digital elevation models and well logs
• Evaluates vulnerability based on five derived criteria: distance to coast, land slope, development density, non-residential groundwater use, and static water level
• Last updated on April 17, 2026

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to open_canada
