The General Quality test’s overall aim is to assess if the impact of groundwater pollution is sufficiently widespread to compromise the use of the groundwater resource either currently or in the future. It is not intended to assess local pollution impacts and is one of the five tests developed for groundwater body chemical classification based on WFD requirements and guidance provided at an EC and UK level. (UKTAG, 2012a).
