Baseline England and Wales

Piper diagram

BGS carried out investigations of the baseline quality of groundwater in aquifers of England and Wales between the late 1990s and 2015. A series of 23 reports and an overall synthesis report were produced as part of this investigation in a collaboration between BGS and the Environment Agency between 2002 and 2005. These are available for download below.
