| The vulnerability map has a 2-color-scale. The green areas show where the aquifer thickness is >30m AND the aquitards total thickness >10m. These areas are considered **protected**. The red areas shows where the aquifer thickness is >30m but the aquitards total thickness <10m. These areas are considered **not protected**. The un-colored parts of the map are where the aquifer thickness is <30m - defined as places where the thickness of sand2 is so small that it is not considered as an aquifer of interest.\\ | The vulnerability map has a 2-color-scale.

| The thickness map shows the thickness of the protective layers (the aquitards), at places where the aquifer and the aquitards are thick enough to be considered. These places correspond to the green spots at the vulnerability map. Therefore, the minimun thickness in this case is 10 m which were defined in the wizard earliere. It is possible to change the color scales values and colors in the “layer properties” on the map.\\ | The thickness map shows the thickness of the protective layers (the aquitards), at places where the aquifer and the aquitards are thick enough to be considered.
