Yonge Street Aquifer (YSA) Well Capacity Restoration Project Status Update March




1) Class Environmental Assessment

York Region is in the process of confirming the Recommended Preferred Solution, which consists of rehabilitating existing municipal wells in Aurora and Newmarket and constructing new wells in Aurora and East Gwillimbury. Ongoing and upcoming activities are as follows:

  • Large-diameter test well drilling and testing program to confirm the Preferred Solution (Phase 2)

2) Groundwater Exploration Program and Other Field Work

The next phase of the groundwater exploration program includes drilling a large-diameter test well at each of the two preferred test sites. Additional tests will be conducted on the wells to confirm the quantity of water available and to monitor surrounding environmental features. 

Updates for each site are provided below:

Aurora:

Well Area 11 –Aurora Well No. 5 Test Site (existing municipal well site, 256 Old Yonge Street at Yonge Street & St John’s Sideroad)
