The Water Framework Directive (2000/60/EC) and Groundwater Daughter Directive (2006/118/EC) (GDD) require Member States to prevent inputs of hazardous substances into groundwater subject to various exemptions. The documents below set out the list of standards that can be used to assess inputs of hazardous substances into groundwater.
Details of how each UK environment agency will implement these standards can be found at the links below.
