Relative Seawater Intrusion Vulnerability

A GIS-based approach for broadly evaluating the relative vulnerability of bedrock coastal aquifers to seawater intrusion in unserviced areas of the province was developed. The approach uses available provincial spatial datasets, such as digital elevation models, civic address points and well logs data, to evaluate relative vulnerability based on the following derived criteria: distance to the coast, land slope, development density, non-residential groundwater use and static water level.
