The aquifer designation dataset has been created by the Environment Agency and British Geological Survey and identifies the different aquifers of England and Wales.
From 1 April 2010 the Environment Agency's Groundwater Protection Policy will be using aquifer designations that are consistent with the Water Framework Directive.
These designations reflect the importance of aquifers in terms of groundwater as a resource (drinking water supply) but also their role in supporting surface water flows and wetland ecosystems.
The maps are split into two different type of aquifer designation:
- Superficial (drift) — permeable unconsolidated (loose) deposits. For example, sands and gravels
- Bedrock — solid permeable formations e.g. sandstone, chalk and limestone
The maps display the following aquifer designations:
- Principal aquifers
- Secondary aquifers (further subdivided into Secondary A, Secondary B, and Secondary Undifferentiated)
- Unproductive strata
The dataset is available to view on the Environment Agency's 'What's in your back yard?' service.
