Polygon file displaying Intake Protection Zones (IPZ).
NOTE 1: CTC has several combined IPZ 1 and 2 features associated with more than 1 intake. For these, the intake ID was coded as NULL. All CTC IPZ 3's are associated with multiple intakes, therefore all the IPZ-3 intake IDs are coded as NULL.
NOTE 2: the City of Toronto chose to use the actual length and location of the diffuser (new Ashbridges Bay WWTP IPZ 3).

Three zones, from the closest to the farthest from the intake, rate the vulnerability threat. IPZ-1: FIRST ZONE around intake, very vulnerable to contamination. Direct and immediate impacts are possible as there is no time to take mitigating action.IPZ-2: SECOND ZONE around the intake where direct impacts are possible because contaminants may reach intake within 2 hours. IPZ-3: THIRD ZONE and the 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.</SPAN></P><TABLE><TBODY><TR><TD><P STYLE="text-align:Center;font-style:italic;font-weight:bold;margin:0 0 4 0;"><SPAN><SPAN>#</SPAN></SPAN></P></TD><TD><P STYLE="text-align:Center;font-style:italic;font-weight:bold;margin:0 0 4 0;"><SPAN><SPAN>ATTRIBUTE/COLUMN NAME</SPAN></SPAN></P></TD><TD><P STYLE="text-align:Center;font-style:italic;font-weight:bold;margin:0 0 4 0;"><SPAN><SPAN>DATATYPE</SPAN></SPAN></P></TD><TD><P STYLE="text-align:Center;font-style:italic;font-weight:bold;margin:0 0 4 0;"><SPAN><SPAN>REQ</SPAN></SPAN></P></TD><TD><P STYLE="text-align:Center;font-style:italic;font-weight:bold;margin:0 0 4 0;"><SPAN><SPAN>DESCRIPTION</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="text-align:Center;"><SPAN><SPAN>1</SPAN></SPAN></P></TD><TD><P><SPAN><SPAN>OGF ID</SPAN></SPAN></P><P><SPAN><SPAN>OBJECTID</SPAN></SPAN></P></TD><TD><P STYLE="text-align:Center;margin:4 0 4 0;"><SPAN><SPAN>NUMBER(13)</SPAN></SPAN></P></TD><TD><P STYLE="text-align:Center;margin:4 0 4 0;"><SPAN><SPAN>Yes</SPAN></SPAN></P></TD><TD><P STYLE="margin:4 0 4 0;"><SPAN><SPAN>A unique numeric provincial identifier assigned to each object.</SPAN></SPAN></P></TD></TR><TR><TD><P STYLE="text-align:Center;"><SPAN><SPAN>2</SPAN></SPAN></P></TD><TD><P><SPAN><SPAN>Source Protection Area ID</SPAN></SPAN></P><P><SPAN><SPAN>SPA_ID</SPAN></SPAN></P></TD><TD><P STYLE="text-align:Center;margin:4 0 4 0;"><SPAN><SPAN>NUMBER(2)</SPAN></SPAN></P></TD><TD><P STYLE="text-align:Center;margin:4 0 4 0;"><SPAN><SPAN>Yes</SPAN></SPAN></P></TD><TD><P STYLE="margin:4 0 4 0;"><SPAN>Identifier for the source protection area that provided the original data about the feature.
