This interactive map works similarly to other mapping applications you have used. You can navigate around and zoom in and out. Click or touch on the location you are interested in, and a popup will appear showing contact information for active Nitrate Management Zones.
The Management Zones are color coded to make their boundaries clear. The priority 2 areas are orange; Nitrate Management Zones have not been established yet in these areas. Locations supplied by municipal water supplies are grey and not covered by the Nitrate Control Program (If you are in one of these areas, an easy way to tell is if you or your landlord pays a monthly water bill). The other colors show active Management Zones.
