Significant impacts on groundwater
Where groundwater and surface waters are connected, the quality and quantity of groundwater can impact ecosystems. ... For example, polluted groundwater can affect freshwater ecosystems like wetlands or rivers, while over-abstraction may reduce the amount of groundwater so that the associated ecosystem dries out. ...

Groundwater quantitative status
Assessment is based on the changes in groundwater level. ... If the groundwater resources are over-abstracted, so that the amount of water used is more than that which is recharged, the groundwater body fails to meet good quantitative status. ... The quantitative status of groundwater can also fail if ecosystems dependent on groundwater deteriorate owing to there not being enough groundwater. ...
