As part of this decommissioning the Groundwater Vulnerability Maps will be removed on Thursday 10 August 2017.

The Groundwater Vulnerability Maps can be found on Defra's Magic Map from the Wednesday 9 August.



We are currently updating our groundwater vulnerability maps to reflect improvements in data mapping and understanding of the factors affecting vulnerability. The new maps will be released later in 2017.

The ‘New groundwater vulnerability mapping methodology’ report provides technical information about how the new maps have been created.
The user guide outlines the kinds of activities the new maps can be used for.
These reports have been published on GOV.UK in advance of the release of the new maps to give users time to understand the new approach and how this differs from the previous groundwater vulnerability maps.
