- Environmental pollution
- Overexploited groundwater
- Inadequate strategy
Area Typology
- Rural area
- Agricultural area
- Other (Please specify below)

Main beneficiaries
- Water Utilities
- Local Population
- Municipalities
- Farmers
- Householders
- Management Authorities
Impact on the beneficiaries of your Best Practice:
The BP is one of the mitigation option to reduce nitrate contamination in NVZ. In long term it can contribute to solving the groundwater pollution issue, which currently entails (due to the application of the Nitrate Directive) a series of constraints on the economic activity of farmers (eg. increase in production costs).
Funding

Description of the innovative component:
Compared to the FIA systems which have already been implemented in Veneto, the FIA under implementation in Arborea includes a technical innovation represented by the Passive Treatment System to be installed within each recharge trench to improve the recharge water quality and reduce the clogging processes at the infiltrating surface.
Obstacles to implementation
- Lack of an adequate regulatory framework
- Other (Please specify below)
- As the BP is innovative in Sardinia, it didn't fit in a clear regulatory framework. Many local authorities were engaged to provide their authorisation to proceed.
Obstacles to funding
Delays in the implementation of the BP (unclear regional legislation, which made the attribution of competences complicated and required the intervention of numerous local authorities called to provide their authorization).
How your Best Practice is economically feasible ?
Use of low cost materials that can be easily found in the local market.Result of this assessment

Validation/upscaling
No
Potentiel of exploitation/outscaling
Yes, in similar hydrogeological context.
Lessons learnt
It is possible to adopt low-cost nature based solution to have a positive impact on the environment.
Recommandations
Before designing such a kind of system it is necessary to have a complete knowledge framework in terms of geology, hydrogeology and hydrogeochemistry in order to understand if the area meets the…
