Member States have delineated groundwater bodies in the river basin districts and reported different data to characterize water bodies such as area, aquifer type and productivity. The dashboards below provide an overview of different results related to delineation of groundwater bodies.

In this page:

1. Groundwater bodies: Number and size [table]

2. Groundwater bodies: Number and size, by geological formation [table]

3. Change in the delineation of groundwater bodies in the 2nd and 1st RBMPs: country comparison [chart]

4. Change in the delineation of groundwater bodies in the 2nd and 1st RBMP, by geological formation [chart]

Disclaimer
Caution is advised when comparing Member States and when comparing the first and second RBMPs, as the results are affected by the methods Member States have used to collect data and often cannot be compared directly.
