Click to view Metadata The Intake Protection Zone is the area around an intake pipe in a lake or river that draws in the surface water used to supply the municipal drinking water system. Three zones, from the closest to the farthest from the intake, rate the vulnerability threat. The IPZ-1 is the FIRST ZONE around an intake, and is very vulnerable to contamination. Direct and immediate impacts are possible as there is no time to take mitigating action. NOTE: IPZ-1 features were not combined resulting in overlapping IPZ-1 features for the Oshawa Water System.
