Service Description: The HVA layer was developed to satisfy requirements of the Source Protection Plan for the Credit Valley, Toronto and Region and Central Lake Ontario region (CTC-SPC 2015) under the Clean Water Act (2006). Here aquifers are defined as water-bearing permeable rock, fractures within rocks, or loose materials (such as gravel, sand, or silt). Vulnerability of aquifers is considered to be related to the depth to aquifer, soil type and thickness to provide an indication of the potential protection provided by materials above the aquifer (CTC-SPC 2015). Details of the methodology used to develop this layer can be found in CTC-SPC (2015).
