Access the Environment Agency’s groundwater SPZs on MagicMap.
To find the SPZs, from the table of contents on the left hand side, select in this order:
- land-based designations
- source protection zones merged (England) – tick the box
Enter your post code and size the map. You can use the transparency slider bar under the ‘designations’ sub-heading to adjust visibility of place names within the zones.
The leaflet explains the Environment Agency’s national dataset of groundwater SPZ maps. We use them when we respond to development enquiries.
The science report sets out our methods for defining groundwater SPZs.
