The Region of Peel's Private Well Abandonment Program (PDF 135KB) decommissions old, unused private wells in Caledon, rural Brampton and Mississauga.
The program’s purpose is to protect Peel’s groundwater sources. Old and unused wells threaten groundwater sources by allowing pollutants such as chemicals and bacteria to contaminate groundwater, a drinking water source for most Region of Peel residents.
