The Oak Ridges Moraine is composed of 200 metres of unconsolidated glacial deposits over bedrock.

The CAMC has developed digital models of geological and hydrogeological subsurface layers across the ORM and it’s drainage areas across the Golden Horseshoe.

Who’s It For?

Layer depth, thickness, and composition at various points allows CAMC geoscientists to interpolate a 3D strata model which can be used to interpret geological variability at different sites.

Policymakers benefit from info about groundwater flow direction, recharge and discharge rates and hydraulic conductivity at different layers to pinpoint vulnerable areas and potential sites for higher capacity wells.
