Description: Highly Vulnerable Aquifers of the Toronto & Region Source Protection Authority Highly Vulnerable Aquifers are aquifers that are more susceptible to contamination because of their location. In general, an HVA will consist of source granular aquifer materials (e.g. sand and/or gravel) or fractured rock that has a high permeability and is exposed near the ground surface with a relatively shallow water table.
