Three zones, from the closest to the farthest from the intake, rate the vulnerability threat. The IPZ-3 is the THIRD ZONE and largest zone around the intake where activities can impact the source water, but there is time to take action to ensure the intake and municipal water is not impacted. NOTE: A null value in the Intake Identifier (Intake_ID) indicates that IPZ-3 feature is associated with more than 1 intake.
