FWC-NbS 3: Aquifer (Type B)
Location: Sardinia, Italy
Climate: Hot-summer Mediterranean climate
Area: 6000 Ha
Objectives: Improve groundwater quality and storage with low-cost and more efficient technological solutions.
Challenges: Water quality; diffuse contamination of aquifers with nitrates; soil fertility management
Description: The Arborea farming district represents one of the most productive agricultural sites in Italy and is identified as a Nitrates Vulnerable Zone (NVZ). It is located on a plain surrounded by marsh wetlands which are protected under the EU Natura 2000 directive and the Ramsar convention. There is a sandy and alluvial aquifer connected to each other. Some projects have been implemented to mitigate the high nitrate groundwater contamination (RE-LIVE, MEDISS). Currently, A MAR pilot system through the technique Forested Infiltration Area (FIA) is being tested as best practice in the sandy phreatic aquifer within the MENAWARA project.
