Nitrates are Catalonia’s most important groundwater pollution problem. 41% of Catalan groundwaters are in a bad status (nitrate concentrations over 50 mg/L). The origin of this pollution is primarily agricultural (Agencia Catalana del Agua, 2016).
Water Framework Directive 2000/60/CE
Directive 2006/118/EC, for the protection of groundwaters.
Atmospherical ammonia can increase particulate matter concentrations, with serious health implications. Ammonia emissions are sourced by agricultural and industrial activities.
Directive 2008/50/CE, for air quality
Wetlands are able to remove nitrogen effectively
To restore wetlands in key areas within an agricultural watershed, in order to intercept the highest possible proportion of nitrate. Therefore, working at the landscape scale is the optimal.
Currently we are talking with landowners of fields within the study area, specifically selected due to their suitable hydrogeological characteristics.
We wish to frame this project within the Natural Climate Solutions strategy.
